* Author: R L Aurbach CR&DS MIS Group 18-Aug-1986

/*
* Function Glo_Command - Documentation Section
*
* Discussion:
* This routine uses lib$get_foreign to read the command line. It
* prefixes the command line with "GloTeX ", so that the CLI routines
* will have the appropriate information on which to operate. It then
* parses the command line and returns the appropriate information to the
* program.
*
* Since the routine establishes LIB$SIG_TO_STOP as a condition handler,
* syntax errors detected during processing result in program exit.
*
* Calling Synopsis:
* Call Glo_Command ()
*
* Inputs:
* none
*
* Outputs:
* none
*
* Return Value:
* none
*
* Global Data:
* infile -> contains the name of the input file as an ASCIZ string.
*
* flag -> indicates the value of the /STYLE qualifier.
*
* filelist -> is updated to contain a list of file specifications.
*
* Files Used:
* none
*
* Assumed Entry State:
* GloTeX is invoked as a foreign DCL command.
*
* Normal Exit State:
* The routine returns to the caller. The global variables are set up
* appropriately.
*
* Error Conditions:
* For the majority of the processing of the routine, LIB$SIG_TO_STOP
* is established as the condition handler. Therefore, any errors cause
* an immediate exit.
*
* Algorithm:
* A. Call Lib$Get_Foreign to retrieve the command line.
* B. Prefix the command line with the command verb.
* C. Call Cli$DCL_Parse to parse the command line.
* D. Process the file name.
* 1. Get the file name.
* 2. Convert it to an ASCIZ string.
* E. Process the /STYLE qualifier.
* F. Process the /GLOSSARY qualifier.
*
* Special Notes:
* This routine is based on the LIB_PARSE_FOREIGN routine, suitably
* modified.
