/* DEVICE I A string specifying an output device. */
/* LINE I A line of text to be output. */
/* FILEN P Maximum length of a file name. */
/* $ Detailed_Input */
/* LINE is a line of text to be written to the output */
/* device specified by DEVICE. */
/* DEVICE is the output device to which the line of text */
/* will be written. */
/* Possible values and meanings of DEVICE are: */
/* a device name This may be the name of a */
/* file, or any other name that */
/* is valid in a FORTRAN OPEN */
/* statement. For example, on a */
/* VAX, a logical name may be */
/* used. */
/* The device name must not */
/* be any of the reserved strings */
/* below. */
/* 'SCREEN' The output will go to the */
/* terminal screen. */
/* 'NULL' The data will not be output. */
/* 'SCREEN' and 'NULL' can be written in mixed */
/* case. For example, the following call will work: */
/* CALL WRLINE ( 'screEn', LINE ) */
/* $ Detailed_Output */
/* None. */
/* $ Parameters */
/* FILEN is the maximum length of a file name. */
/* $ Exceptions */
/* This routine is a special case as far as error handling */
/* is concerned because it is called to output error */
/* messages resulting from errors detected by other routines. */
/* In such a case, calling SIGERR would constitute recursion. */
/* Therefore, this routine prints error messages rather */
/* than signalling errors via SIGERR and setting the long */
/* error message via SETMSG. */
/* The following exceptional cases are treated as errors: */
/* 1) SPICE(NOFREELOGICALUNIT) -- No logical unit number */
/* is available to refer to the device. */
/* 2) SPICE(FILEOPENFAILED) -- General file open error. */
/* 3) SPICE(FILEWRITEFAILED) -- General file write error. */
/* 4) SPICE(INQUIREFAILED) -- INQUIRE statement failed. */
/* 5) Leading blanks in (non-blank) file names are not */
/* significant. The file names */
/* 'MYFILE.DAT' */
/* ' MYFILE.DAT' */
/* are considered to name the same file. */
/* 6) If different names that indicate the same file are supplied */
/* to this routine on different calls, all output associated */
/* with these calls WILL be written to the file. For example, */
/* on a system where logical filenames are supported, if */
/* ALIAS is a logical name pointing to MYFILE, then the calls */
/* CALL WRLINE ( 'MYFILE', 'This is the first line' ) */
/* CALL WRLINE ( 'ALIAS', 'This is the second line' ) */
/* will place the lines of text */
/* 'This is the first line' */
/* 'This is the second line' */
/* in MYFILE. See $Restrictions for more information on use */
/* of logical names on VAX systems. */
/* $ Files */
/* 1) If DEVICE specifies a device other than 'SCREEN' or 'NULL', */
/* that device is opened (if it's not already open) as a NEW, */
/* SEQUENTIAL, FORMATTED file. The logical unit used is */
/* determined at run time. */
/* $ Particulars */
/* If the output device is a file that is not open, the file will */
/* be opened (if possible) as a NEW, sequential, formatted file, */
/* and the line of text will be written to the file. If the file */
/* is already opened as a sequential, formatted file, the line of */
/* text will be written to the file. */
/* Use the entry point CLLINE to close files opened by WRLINE. */
/* $ Examples */
/* 1) Write a message to the screen: */
/* CALL WRLINE ( 'SCREEN', 'Here''s a message.' ) */
/* The text */
/* Here's a message. */
/* will be written to the screen. */
/* 2) Write out all of the elements of a character string array */
/* to a file. */
/* CHARACTER*(80) STRING ( ASIZE ) */
/* . */
/* . */
/* . */
/* DO I = 1, ASIZE */
/* CALL WRLINE ( FILE, STRING(I) ) */

/* C Ask the user whether verbose program output is */
/* C desired. Set the output device accordingly. */

/* - SPICELIB Version 4.0.0, 07-APR-1998 (NJB) */
/* References to the PC-LINUX environment were added. */
/* The write format for the case where the output device is the */
/* screen has been made system-dependent; list-directed output */
/* format is now used for systems that require a leading carriage */
/* control character; other systems use character format. The */
/* write format for the case where the output device is a file */
/* has been changed from list-directed to character. */
/* - SPICELIB Version 3.0.0, 11-NOV-1993 (HAN) */
/* Module was updated to include the value for FILEN */
/* and the appropriate OPEN statement for the Silicon */
/* Graphics, DEC Alpha-OSF/1, and NeXT platforms. The previous */
/* value of 256 for Unix platforms was changed to 255. */
/* - SPICELIB Version 2.1.0, 13-OCT-1992 (HAN) */
/* Module was updated to include the value of FILEN for the */
/* Hewlett Packard UX 9000/750 environment. */
/* The code was also reformatted so that a utility program can */
/* create the source file for a specific environment given a */
/* master source file. */
/* - SPICELIB Version 2.0.0, 25-MAR-1991 (NJB) */
/* 1) This routine now can write to files that have been opened */
/* by other routines. WRLINE uses an INQUIRE statement to */
/* determine whether the file indicated by DEVICE is open, */
/* and if it is, WRLINE does not attempt to open it. This */
/* allows use of WRLINE to feed error output into a log file */
/* opened by another routine. */
/* The header has been updated accordingly. */
/* This fix also fixes a bug wherein this routine would treat */
/* different character strings naming the same file as though */
/* they indicated different files. */
/* 2) The limit imposed by this routine on the number of files it */
/* can open has been removed. The file database used in */
/* previous versions of this routine is no longer used. */
/* 3) On VAX systems, this routine now opens the output file */
/* (when required to do so) as a normal text file. */
/* 4) Improper treatment of the case where DEVICE is blank was */
/* remedied. Any value of DEVICE that is not equal to */
/* 'SCREEN' or 'NULL' after being left-justified and */
/* converted to upper case is considered to be a file name. */
/* 5) Unneeded variable declarations and references were removed. */
/* The arrays called STATUS and FILES are not needed. */
/* 6) All instances if "PRINT *" have been replaced by */
/* "WRITE (*,*)" because Language Systems Fortran on the */
/* Macintosh interprets "PRINT *" in a non-standard manner. */
/* 7) Use of the EXIST specifier was added to the INQUIRE */
/* statement used to determine whether the file named by */
/* DEVICE is open. This is a work-around for a rather */
/* peculiar behavior of at least one version of Sun Fortran: */
/* files that don't exist may be considered to be open, as */
/* indicated by the OPENED specifier of the INQUIRE statement. */
/* 8) One other thing: now that LJUST and UCASE are error-free, */
/* WRLINE uses them; this simplifies the code. */
/* - Beta Version 1.2.0, 27-FEB-1989 (NJB) */
/* Call to GETLUN replaced by call to FNDLUN, which is error-free. */
/* Call to IOERR replaced with in-line code to construct long */
/* error message indicating file open failure. Arrangement of */
/* declarations changed. Keywords added. FILEN declaration */
/* moved to "declarations" section. Parameters section added. */
/* - Beta Version 1.1.0, 06-OCT-1988 (NJB) */
/* Upper bound of written substring changed to prevent use of */
/* invalid substring bound. Specifically, LASTNB ( LINE ) was */
/* replaced by MAX ( 1, LASTNB (LINE) ). This upper bound */
/* now used in the PRINT statement as well. */

/* VARIABLE I/O DESCRIPTION */
/* -------- --- -------------------------------------------------- */
/* FILE I The name of a file to be examined. */
/* ARCH O The architecture of the kernel file. */
/* KERTYP O The type of the kernel file. */
/* $ Detailed_Input */
/* FILE is the name of a SPICE kernel file whose architecture */
/* and type are desired. */
/* $ Detailed_Output */
/* ARCH is the file architecture of the SPICE kernel file */
/* specified be FILE. If the architecture cannot be */
/* determined or is not recognized the value '?' is */
/* returned. */
/* Architectures currently recognized are: */
/* DAF - The file is based on the DAF architecture. */
/* DAS - The file is based on the DAS architecture. */
/* XFR - The file is in a SPICE transfer file format. */
/* DEC - The file is an old SPICE decimal text file. */
/* ASC -- An ASCII text file. */
/* KPL -- Kernel Pool File (i.e., a text kernel) */
/* TXT -- An ASCII text file. */
/* TE1 -- Text E-Kernel type 1. */
/* ? - The architecture could not be determined. */
/* This variable must be at least 3 characters long. */
/* KERTYP is the type of the SPICE kernel file. If the type */
/* can not be determined the value '?' is returned. */
/* Kernel file types may be any sequence of at most four */
/* printing characters. NAIF has reserved for its use */
/* types which contain all upper case letters. */
/* A file type of 'PRE' means that the file is a */
/* pre-release file. */
/* This variable may be at most 4 characters long. */
/* $ Parameters */
/* RECL is the record length of a binary kernel file. Each */
/* record must be large enough to hold 128 double */
/* precision numbers. The units in which the record */
/* length must be specified vary from environment to */
/* environment. For example, VAX Fortran requires */
/* record lengths to be specified in longwords, */
/* where two longwords equal one double precision */
/* number. */
/* $ Exceptions */
/* 1) If the filename specified is blank, then the error */
/* SPICE(BLANKFILENAME) is signaled. */
/* 2) If any inquire on the filename specified by FILE fails for */
/* some reason, the error SPICE(INQUIREERROR) is signaled. */
/* 3) If the file specified by FILE does not exist, the error */
/* SPICE(FILENOTFOUND) is signaled. */
/* 4) If the file specified by FILE is already open but not through */
/* SPICE interfaces, the error SPICE(EXTERNALOPEN) is signaled. */
/* 5) If an attempt to open the file specified by FILE fails when */
/* this routine requires that it succeed, the error */
/* SPICE(FILEOPENFAILED) is signaled. */
/* 6) If an attempt to read the file specified by FILE fails when */
/* this routine requires that it succeed, the error */
/* SPICE(FILEREADFAILED) is signaled. */
/* 7) Routines in the call tree of this routine may trap and */
/* signal errors. */
/* 8) If the ID word in a DAF based kernel is NAIF/DAF, then the */
/* algorithm GETFAT uses to distinguish between CK and SPK */
/* kernels may result in an indeterminate KERTYP if the SPK or */
/* CK files have invalid first segments. */
/* $ Files */
/* The SPICE kernel file specified by FILE is examined by this */
/* routine to determine its architecture and type. If the file */
/* named by FILE is not connected to a logical unit or loaded */
/* in the handle manager, this routine will OPEN and CLOSE it. */
/* $ Particulars */
/* This subroutine is a support utility routine that determines the */
/* architecture and type of a SPICE kernel file. */
/* $ Examples */
/* Suppose you wish to write a single routine for loading binary */
/* kernels. You can use this routine to determine the type of the */
/* file and then pass the file to the appropriate low level file */
/* loader to handle the actual loading of the file. */
/* CALL GETFAT ( FILE, ARCH, KERTYP ) */
/* IF ( KERTYP .EQ. 'SPK' ) THEN */
/* CALL SPKLEF ( FILE, HANDLE ) */
/* ELSE IF ( KERTYP .EQ. 'CK' ) THEN */
/* CALL CKLPF ( FILE, HANDLE ) */
/* ELSE IF ( KERTYP .EQ. 'EK' ) THEN */
/* CALL EKLEF ( FILE, HANDLE ) */
/* ELSE */
/* WRITE (*,*) 'The file could not be identified as a known' */
/* WRITE (*,*) 'kernel type. Did you load the wrong file' */
/* WRITE (*,*) 'by mistake?' */
/* END IF */
/* $ Restrictions */
/* 1) In order to properly determine the type of DAF based binary */
/* kernels, the routine requires that their first segments and */
/* the meta data necessary to address them are valid. */

/* UTCST, */
/* UTHAN, */
/* UTLCK, */
/* UTLUN are the arrays respectively containing the cost, */
/* handle, locked, and logical unit columns of the unit */
/* table. If ZZDDHF2H requires a logical unit, then */
/* it will borrow one from the unit table. Depending */
/* on the state of the table passed in from the caller */
/* one of three possible scenarios may occur (Recall */
/* that 'zero-cost' rows are ones whose units are */
/* reserved with RESLUN and not currently connected */
/* to any file.) */
/* A 'zero-cost' row exists in the table, in */
/* which case the row is used temporarily and */
/* may be removed depending on the number of entries */
/* in the file table (NFT). */
/* The unit table is full (NUT=UTSIZE), in which */
/* case the unit with the lowest cost that is not */
/* locked to its handle will be disconnected, used, */
/* and then returned to the table as a 'zero-cost' */
/* row before returning to the caller. */
/* The unit table is not full (NUT<UTSIZE) and there */
/* are no 'zero-cost' rows. In this case NUT is */
/* temporarily increased by one, and the new row */
/* is used. After this routine no longer requires */
/* the unit, depending on the number of entries in */
/* the file table (NFT) the row may be left in the */
/* table as a 'zero-handle' row or removed entirely. */
/* In the event an error is signaled, the contents of the */
/* unit table are placed into a usable state before */
/* returning to the caller. */
/* NUT is the number of entries in the unit table. Since */
/* this routine borrows a unit from the unit table, which */
/* may involve allocation of a new unit, this value may */
/* change. */
/* EXISTS is a logical if set to TRUE, indicates that FNAME */
/* exists. If FALSE, FNAME does not exist. In the event */
/* an exception is signaled the value is undefined. */
/* OPENED is a logical if set to TRUE, indicates that FNAME */
/* is opened and attached to a logical unit. If FALSE, */
/* FNAME is not attached to a unit. In the event an */
/* exception is signaled the value is undefined. */
/* HANDLE is the handle in the file table associated with */
/* FNAME. If FOUND is FALSE, then HANDLE is returned as */
/* 0. */
/* FOUND is a logical if TRUE indicates that FNAME was found */
/* in the file table. If FALSE indicates that it was not */
/* located. */
/* MNM is a unique (enough) DP number -- the Magic NuMber -- */
/* associated with FNAME computed by this examining the */
/* file contents. */
/* $ Parameters */
/* None. */
/* $ Exceptions */
/* 1) If any of the INQUIRE statments this routine performs fail, */
/* the error SPICE(INQUIREFAILED) is signaled. FOUND is set to */
/* FALSE and HANDLE to 0. */
/* 2) If the attempt to open FNAME fails, then SPICE(FILEOPENFAILED) */
/* is signaled. FOUND is set to FALSE, and HANDLE to 0. */
/* 3) If FNAME is determined not to be loaded into the file table */
/* then FOUND is set to FALSE and HANDLE is set to 0. */
/* $ Files */
/* If the file named by FNAME is not connected to a logical unit, */
/* this routine will open it for direct access to complete its */

/* $ Detailed_Input */

/* $ Detailed_Output */
/* UNIT is the number of a free logical unit (also called */
/* an "external unit"). A "free" logical unit is one */
/* that is not reserved and is not currently connected to */
/* and open file. If no free units are available, the */
/* value of UNIT is 0. */
/* $ Parameters */
/* MINLUN is the minimum logical unit number. The Fortran */
/* standard states that unit numbers must be zero or */
/* positive. However, the value 0 is reserved as a */
/* status code for this routine, so MINLUN must be */
/* assigned a value greater than 0. */
/* MAXLUN is the maximum logical unit number allowed by the */
/* VAX Fortran compiler. This may differ for other */
/* machines. */
/* Listed below are the values for several machines: */
/* Environment: VAX/VMS, VAX FORTRAN */
/* MINLUN: 1 */
/* MAXLUN: 99 */

/* * 32767 is the actual value a logical unit may be assigned to */
/* on the IBM PC, however, using this value increases the memory */
/* requirements of a program calling this routine by 128K. */
/* $ Exceptions */
/* Error free. */
/* 1) If no logical units are available, UNIT is set equal */
/* to 0. */
/* 2) This routine performs a Fortran INQUIRE operation. If */
/* the INQUIRE fails, UNIT is set equal to the negative */
/* of the INQUIRE iostat ( UNIT will thus have a negative */
/* value). */
/* $ Files */
/* None. */
/* $ Particulars */
/* FNDLUN returns the number of the first (unreserved) unit not */
/* currently connected to a file. It thus frees the user from */
/* having to maintain an accounting of which units are open, which */
/* are closed, and which are available. */
/* This routine is related to the routines GETLUN, RESLUN, and */
/* FRELUN. Together, these routines support coordinated usage of */
/* Fortran logical units. FNDLUN (Find a free logical unit) and */
/* GETLUN (Get a free logical unit) both have the function of */
/* returning a logical unit number that is not reserved or already */
/* in use. The principal difference between the functionality of */
/* these routines is that GETLUN both returns a status code and */
/* signals an error if a free unit is not found, while FNDLUN */
/* merely returns a status code. */
/* RESLUN is used to reserve logical unit numbers, so that they will */
/* not be returned by GETLUN or FNDLUN; FRELUN frees logical units */
/* previously reserved via calls to RESLUN. */
/* On the VAX, SUN, PC, and HP logical units 5-7 are reserved by */
/* default. On the Macintosh logical units 5,6 and 9 are reserved */
/* by default. Other units may be reserved by calling RESLUN. Once */
/* reserved, units (except ones reserved by default) may be */
/* unreserved by calling FRELUN. */
/* To reserve logical unit numbers for special use, refer to */
/* RESLUN. To make reserved units available to FNDLUN and GETLUN, */
/* refer to FRELUN. */
/* A unit returned by FNDLUN does NOT automatically become a */
/* reserved unit. If the user wishes to reserve a unit found by */
/* FNDLUN, the call to FNDLUN must be followed by a call to RESLUN. */
/* Note that although 0 is a valid logical unit number on some */
/* systems, a value of 0 returned by FNDLUN indicates that no free */
/* logical unit was available, rather than that logical unit 0 is */
/* available. Similarly, negative values returned by FNDLUN are */
/* status codes, not logical unit numbers. */
/* $ Examples */
/* The following code fragment illustrates the use of FNDLUN. */
/* CALL FNDLUN ( UNIT ) */
/* IF ( UNIT .LT. 0 ) THEN */
/* RETURN */
/* END IF */
/* $ Restrictions */
/* This routine never returns logical unit numbers that are less */
/* than or equal to 0. */
