-Brief_I/O

   VARIABLE  I/O  DESCRIPTION
   --------  ---  --------------------------------------------------
   op         I   The operation:  "GET" or "SET".
   lenout     I   Length of list for output.
   list      I/O  Specification of error messages to be output.

-Detailed_Input

   op      indicates the operation to be performed.  Possible
           values are "GET" and "SET".

           "SET" means, "the following list specifies the default
           selection of error messages to be output."  These are
           the messages that will be output to the default error
           output device (selected by errdev_c) when an error is
           detected.

           "GET" means, "return the current list of error output
           items."  This is the exact list that was set by the
           last call to this routine with the "SET" option.

           The option can be specified in mixed case.  For example,
           the following call will work:

           errprt_c ( "SeT", lenout, "ALL" )


   lenout  is the allowed length of list when list is returning a
           the error message list.  The size described by lenout
           should be large enough to hold any possible output plus 1.


   list    is a list of error message items.  The items
           are delimited by commas.  The items that can be
           in the list are the words:

           1.  SHORT        ...indicates the short error message
           2.  EXPLAIN      ...the explanation of the short message
           3.  LONG         ...the long error message
           4.  TRACEBACK    ...the traceback
           5.  ALL          ...indicates "output all messages"
           6.  NONE         ...indicates "don't output any messages"
           7.  DEFAULT      ...same as ALL, but includes default
                                message

           A "list" is a character string containing some or
           all of the above words, delimited by commas.  Examples
           are:

           1.  "SHORT, EXPLAIN"
           2.  "SHORT, LONG"
           3.  "ALL"
           4.  "NONE"
           5.  "ALL, NONE, ALL, SHORT, NONE"

           Each word in the list can be thought of as
           "flipping a switch" to enable or disable the output
           of the message(s) indicated by the word.  The
           words are acted on in the order they occur in the
           list, starting with the leftmost word.  As examples,
           consider the sample lists above.

           The effect of the first list above, "SHORT, EXPLAIN",
           is to enable the output of the short error message
           and the explanatory text corresponding to it.

           The effect of the second list is to enable the output
           of the short and long messages.

           The effect of the third list is to enable the output of
           all of the error messages (short, long, explanation
           of the short message, and traceback).

           The effect of the fourth list is to disable output of
           all of the messages.

           The effect of the fifth list is to disable output of
           all of the messages.  The reason for this is that
           the words in the list are responded to in order,
           from left to right, and "NONE" is the last word.

           If any words other than SHORT, LONG, EXPLAIN, ALL,
           DEFAULT, TRACEBACK or NONE appear in list, those words
           that are recognized are responded to.  The words
           that are not recognized are diagnosed as
           erroneous, and error messages are generated
           for each such unrecognized word.

           The length of list is caller-defined, but only
           the first 100 characters of list will be saved
           for later retrieval.

           Only the first 10 items in the list are used;
           the rest are ignored.

-Detailed_Output

   list    is a list of error message items.  The value of
           list is that set by the last call to this routine
           using the "SET" option.  See "Detailed Input"
           for a description of the possible values and
           meanings of list.

           The initial value returned is "DEFAULT".

           Only the first 100 characters of list are saved
           when the list is set; any additional characters
           are truncated.  Therefore, the first 100
           characters, at most, of the saved value of list
           will be returned.

-Parameters

   None.

-Exceptions

   1) If the input argument op does not indicate a valid operation,
      the error SPICE(INVALIDOPERATION) will be signaled.
      
   2) If the input argument list does not indicate a valid list of
      error message types, the error SPICE(INVALIDLISTITEM) will be
      signaled.
      
   3) The error SPICE(EMPTYSTRING) is signalled if the input
      string does not contain at least one character, since the
      input string cannot be converted to a Fortran-style string
      in this case.
      
   4) The error SPICE(NULLPOINTER) is signalled if the input string
      pointer is null.
 
   5) The user must pass a value indicating the length of the output
      string, when list is an output.  If this value is not at least 2, 
      the error SPICE(STRINGTOOSHORT) is signaled.

   Also, this routine is part of the CSPICE error
   handling mechanism.

-Files

   None.

-Particulars

   Please read the "required reading"!

   This routine is intended to be used in conjunction with
   errdev_c, which selects the default output device to which
   the error messages selected by this routine will be
   output.

   Additionally, the error response action must be
   something other than "IGNORE" if the error messages
   are to be output.  Possible choices of the error
   response action are "RETURN", "REPORT", "ABORT", "DEFAULT", and
   "IGNORE".  Use erract_c to set the error response action.


   Only the first 100 characters of list are saved.

   The default set of error messages that are output is the
   set specified by "DEFAULT"; i.e., all of them, including
   the "default" message.


-Examples

   1.  In this example, we select as the output device
       the file, SPUD.DAT, and then select the error
       messages to be output.  We choose the short
       error message and the traceback.  Since a
       different set of messages may have been selected
       previously, we clear the old setting by putting
       the word, "NONE", at the beginning of the list.

          /.
          Set the error output device to SPUD.DAT:
          ./
          errdev_c (  "SET", lenout, "SPUD.DAT" );

          /.
          Choose error messages:
          ./
          errprt_c (  "SET", lenout, "NONE, SHORT, TRACEBACK" );


   2.  In this example we are retrieving the error message list.

          /.
          Declare the output string and its size.
          ./

         #define     LENOUT  50

         SpiceChar   list[ LENOUT ];

         errdev_c ( "GET", LENOUT, list );


-Restrictions

   The device to which the selected error messages will
   be written must be selected via errdev_c; otherwise,
   messages will be written to the initial default device.

   Only the first 100 characters of list are saved.

/* $ Version */

/* -    Version 6.0.1, 08-MAY-2001 (BVS) */

/*       Increased LINLEN from 255 to 1000 to make it consistent */
/*       with SPICELIB's SPC* and SUPPORT's DAF* internal line sizes. */

/* -    Version 5.0.1, 21-JUL-1997 (WLT) */

/*       Modified the banner at start up so that the version of the */
/*       toolkit used to link COMMNT will be displayed. */

/*       In addition all WRITE statements were replaced by calls to */
/*       TOSTDO. */

/* -    Version 5.0.0, 05-MAY-1994 (KRG) */

/*       Modified the program to use the new file type identification */
/*       capability that was added to spicelib. No file type menu is */
/*       necessary now, as the file type is determined during the */
/*       execution of the program. */

/*       The prompts for the begin and end markers used to extract a */
/*       subset of text lines from an input comment file which were then */
/*       placed into the comment area of a SPICE binary kernel file have */
/*       been removed. The entire input comment file is now placed into */
/*       the comment area of the binary kernel file. This change */
/*       simplifies the user interaction with the program. */

/*       Added support for the new PCK binary kernel files. */

/*       If an error occurs during the extraction of comments to a file, */
/*       the file that was being created is deleted. We cannot know */
/*       whether the file had been successfully created before the error */
/*       occurred. */

/* -    Version 4.0.0, 11-DEC-1992 (KRG) */

/*        Added code to support the E-Kernel, and redesigned the */
/*        user interface. */

/* -    Version 3.1.0, 19-NOV-1991 (MJS) */

/*        Variable QUIT initialized to FALSE. */

/* -    Version 3.0.1, 10-AUG-1991 (CHA) (NJB) */

/*        Updated comments to reflect status as a Toolkit */
/*        utility program.  Message indicating that no comments */
/*        were found in the specified file was changed to include */
/*        the file name. */

/* -    Version 2.0.0, 28-JUN-1991 (JEM) */

/*        The option to read the comments from the comment */
/*        area of a binary SPK or CK was added to the menu. */

/* -    Version 1.0.0, 05-APR-1991 (JEM) */

/* -& */

/*     SPICELIB functions */


/*     Parameters */

/*     Set the version of the comment program. This should be updated */
/*     every time a change is made, and it should agree with the */
/*     version number in the header. */


/*     Set a value for the logical unit which represents the standard */
/*     output device, commonly a terminal. A value of 6 is widely used, */
/*     but the Fortran standard does not specify a value, so it may be */
/*     different for different Fortran implementations. */


/*     Lower bound for a SPICELIB CELL data structure. */


/*     Maximum number of open binary files allowed. */


/*     Set a value for a replacement marker. */


/*     Set a value for a filename prompt. */


/*     File types */


/*     Set a value for the length of a text line. */


/*     Set a value for the length of an error message. */


/*     Set a value for the length of a filename. */


/*     Set a length for the prompts in the prompt table. */


/*     Set a length for the status of a file: 'OLD' or 'NEW'. */


/*     Set the length for the architecture of a file. */


/*     Set the length for the type of a file. */


/*     Set a length for the option values. */


/*     Set a length for the title of a menu. */


/*     Set a length for an option name (what is typed to select it) */
/*     for a menu. */


/*     Set the length of the text description of an option on a menu. */


/*     The number of options available on the main menu. */


/*     Set up some mnemonics for indexing the prompts in the prompt */
/*     table. */


/*     Set the maximum size of the filename table: this must be the */
/*     number of distinct ``types'' of files that the program may */
/*     require. */


/*     Set up some mnemonics for indexing the messages in the message */
/*     table. */


/*     Set the maximum size of the message table: There should be a */
/*     message for each ``type'' of action that the program can take. */


/*     Set up some mnemonics for the OK and not OK status messages. */


/*     Set the maximum number of status messages that are available. */


/*     We need to have TKVLEN characters to hold the current version */
/*     of the toolkit. */


/*     Variables */


/*     We want to insert a blank line between additions if there are */
/*     already comments in the binary file. We indicate this by giving */
/*     the variable INSBLN the value .TRUE.. */
