/*
* Function Idx_Commmand - Documentation Section
*
* Discussion:
* This routine uses lib$get_foreign to read the command line. It
* prefixes the command line with "IdxTeX ", so that the CLI routines
* will have the appropriate information on which to operate. It then
* parses the command line and returns the appropriate information to the
* program.
*
* Since this routine establishes LIB$SIG_TO_STOP as a condition handler,
* syntax errors detected during processing result in program exit.
*
* Calling Synopsis:
* Call Idx_Command (file, toc_flag, mst_flag)
*
* Inputs:
* none
*
* Outputs:
* file -> is the input file specified in the command line. This
* is a required parameter. This variable is an ASCIZ
* string passed by reference. The calling program is
* responsible for allocating a sufficiently large
* string (i.e., char file[256]).
*
* toc_flag -> indicates whether the /TOC qualifier was specified.
* Values returned are:
* IDX_K_NONE - /TOC not specified.
* IDX_K_ARTICLE - /TOC:ARTICLE specified.
* IDX_K_REPORT - /TOC:REPORT specified.
*
* mst_flag -> indicates whether the /MASTER qualifier was specified.
* Returns a boolean result.
*
* Return Value:
* none
*
* Global Data:
* none
*
* Files Used:
* none
*
* Assumed Entry State:
* IdxTeX is invokes as a Foreign DCL command.
*
* Normal Exit State:
* Routine returns to caller. The "file", "toc_flag", and "mst_flag"
* variables are set up correctly.
*
* Error Conditions:
* Since the routine establishes LIB$SIG_TO_STOP as its exception handler,
* syntax and parsing errors detected by the CLI$ routines (which signal
* errors) cause the program to exit. That is, all syntax errors are
* fatal.
*
* 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 /TOC qualifier.
* 1. If /TOC is not specified,
* a. toc_flag = IDX_K_NONE.
* 2. If /TOC:ARTICLE specified,
* a. toc_flag = IDX_K_ARTICLE.
* 3. If /TOC:REPORT specified.
* a. toc_flag = IDX_K_REPORT.
* F. Process the /MASTER qualifier.
*
* Special Notes:
* This routine is based on the LIB_PARSE_FOREIGN routine, suitably
* modified.
