*N vpfopencheck
*
*::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
*
* Purpose:
*P
* This function tries its darndest to open a file. It initially calls
* fopen with the given filename and mode. If that doesn't work and
* the file is not on the hard disk, it displays a message asking the
* user to enter the correct disk in the drive, waits for either a retry
* or a cancel response, and, if told to retry, tries again. This
* process is repeated until either the file is opened or the user
* requests cancel.
*E
*::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
*
* Parameters:
*A
* filename <input> == (char *) full path name of the file to be opened.
* mode <input> == (char *) mode of the file.
* diskname <input> == (char *) descriptive name of the disk the file is
* on.
* return <output> == (FILE *) file pointer newly associated with
* filename.
