Greetings,
How do you does a program use wild cards from the shell? Does the
shell pass a modified argv to a program or is it up to the program to
expand the wild cards? I hope the shell expands the wild cards for the
program. I am using Wshell on a A3000.
Thanks

The shell does NOT expand wildcards. WShell does not anyway, SKsh does, its a (sorta) implementation of csh on U*IX. This is not the 'amiga way' however. Each program is supposed to do its own wildcard expansion, at least under 1.x of the operating system. Under 2.0 (which is what you're probably running on the 3000) there are new calls in the dos library for command parsing and wildcard expansion. They are quite nice. Unfortunately, I don't think you'll be able to get any docs on them yet. > Thanks > Victor Martinez -- |_o_o|\\ |. o.| || The Jay Denebeim | . | || Software | o | || Distillery | |// Address: UUCP: mcnc.org!deepthot.uucp!jay ====== Internet: jay@deepthot.cary.nc.us BBS:(919)-460-7430 VOICE:(919)-460-6934

Most Amiga shells pass the wildcards to the program, though a few of the UNIX flavored shells may do wildcard expansion for you. Under 2.0, there are DOS library functions to expand wildcards in various ways. There is no such facility in 1.3, though I did a wildcard matching routine for DiskSalv V1.4x, and split off the code as a separate demo which I placed in the public domain. My code only matches 1.3 wildcards; 2.0 adds character sets and negation not part of the 1.3 specification, which I suppose could be hacked into my code (character sets would be easy, negation not-so-easy). This was posted awhile back, but I'll email it to anyone in need. -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "That's me in the corner, that's me in the spotlight" -R.E.M.
