On a UNIX system a command of the form
gawk -f process.awk data*.*
has the wildcard filename expansion dealt with by the UNIX shell.
On an MSDOS system, at least with version 3.xx, there is no such shell
expansion. Instead, wildcards are dealt with *within*each*application*
by first match (INT21H/4EH) and next match (INT21H/4FH).
The 2.02 beta version did that.
The 2.11 version currently on SIMTEL does not: all filenames have to be
explicitly entered.
Is a suitable upgrade on the way?

Sure, here's one that will do all the files ending in the extension .C: for %f in (*.c) do gawk %f There, simple wild card expansion. If you want, you can stick in in a batch file, like this: --- CUT HERE -- FILE GLOB.BAT -- for %%f in (%2 %3 %4 %5 %6 %7 %8 %9) do %1 %%f --- CUT HERE -- FILE GLOB.BAT -- And you can just go: GLOB gawk *.c *.h *.cpp -- -- David Kirsch UUCP: {uunet,ubc-cs}!van-bc!rsoft!mindlink!a563 Voice: (604) 327-4404 a563@mindlink.UUCP Vancouver, British Columbia 'In-no-sense?

Actually, all you have to do is include the proper file during the link phase. If you are using Turbo C, this file is WILDARGS.OBJ. I can't recall the name of the MSC file but it does exist. When included it does the filename expansion and presents the arguments to main like Unix shell does. -- D'Arcy J.M.

Instead, wildcards are dealt with *within*each*application* If you are using Microsoft C, you can include the file SETARGV.OBJ when you link the program together. This file should be on one of your library disks for MSC. Of course, this only gives you wimpy MSDOS wildcard expansion, but it's better than nothing. - - - - - - - - - - Steve Creps creps@silver.ucs.indiana.edu (129.79.1.6) {inuxc,rutgers,uunet!uiucdcs,pur-ee}!iuvax!silver!creps

The 128 byte MSDOS command line puts a nasty limit on the length of the expanded line. The MKS utilities use a non-standard mechanism to get at the shell's expanded command line, but this is inherently nonportable. Nope, under MSDOS you have to do the work yourself. Anyway feel like donating a glob() function to the public domain? Cheers Steve

This will often be enough, but not always, depending on what the awk script does in its END action, for example. Some awk scripts may also need all of the input file names (using ARGV[]) to perform their function. Unfortunately, you're also still stuck with MSDOS's simple wildcard expansion. No character classes, no embedded literals ("*[a-c]x???"), etc. A full-blown UNIX style glob() would allow provide facilities. Cheers, Steve.

WILDCARD.OBJ is present in _all_ versions of Turbo C.

Not sure about the attribute for the quote, but here goes: If you compile GAWK with TURBO-C++ 1.0 then you can link it a special way that allows you to have wildcards to your hearts content.
