00500 DSCR SCNCMD.SAI -- a package for scanning CUSP-like commands.
00600
00700 DES This package provides a function COMMANDSCAN, and a set
00800 of variables and defined values with the following proerties:
00900 PAR The following values must be DEFINEd:
01000 SRCMODE, LSTMODE, RELMODE the data modes for the approp. files
01100 (define them all, even if you don't use them)
01200 SRCEXT, LSTEXT, RELEXT default extension names (they should
01300 expand to string constants) for the appropriate files. Blank
01400 will also be checked as a possible extension for source files.
01500 PROCESSOR should expand to a string constant. The first three
01600 characters will be the name of the TMPCOR command file if started
01700 in RPG mode. nnnprocessor.TMP is the alternate if TMPCOR fails.
01800 SWTSIZ is the maximum number of switches recognized by the PROCESSOR.
01900 GOODSWT is a string which contains the characters which are valid
02000 switches.
02100
02200 The following variables must be set:
02300 ONETIME should be made 0 once only, to force opening of
02400 the command file.
02500 NXTFIL should be made 0 to force COMMANDSCAN to expect
02600 a new FILE_FILE command next, instead of more source files.
02700 WANTBIN should be made true if a `.REL' file is to be
02800 opened if a file is specified for it.
02900 WANTLST should be made true if a `.LST' file is to be
03000 opened if a file is specified for it.
03100 SOURCECOUNT, after the call on COMMANDSCAN, may be changed,
03200 either permanently or temporarily, to control input.
03300 RES on returning from COMMANDSCAN, the following are available:
03400 WANTBIN, WANTLST -- true if a file was opened in the approp.
03500 position, false if false coming in, or no file specified.
03600 BINFIL, SRCFIL -- the file, extension, and PPN for the approp.
03700 files (strings).
03800 SRC, BIN, LST, CMND, DELCHNL (1-5) are channels reserved for
03900 the obvious functions. You should use these names.
04000 CMDTBL, LINTBL, RBRK (15-17) are break tables used by
04100 COMMANDSCAN. Use them if you wish, but don't expect
04200 them to be there when you get back.
04300 CRLF,DSCR, and BLANKS are the obvious macros. Redefine any but DSCR
04400 if you wish.
04500 SID Channels 1-5, Break Tables 15-17 are reserved by
04600 COMMANDSCAN. Do GETCHANs to obtain channels, or
04700 be careful.
04800 CAL call COMMANDSCAN with no parameters. The first time, and
04900 any time subsequently that it is called with NXTFIL=0, it
05000 will expect optional LST and REL specs, separated by comma,
05100 followed by a left arrow in the command file, then one or
05200 more source file names separated by commas, terminated by
05300 a CRLF. Only one source file is read the first time. Subse-
05400 quent calls on COMMANDSCAN (without touching NXTFIL) will
05500 cause subsequent source files to be looked up--if no more exist
05600 an error message will be printed. Set this to FALSE when you
05700 want a brand new command. Set ONETIME once for every time
05800 the entire program is restarted.
