I have a question regarding opening a window on a custom screen. I am using the examples from the "Programmers Guide to the Amiga" , chapter four(pgs 118-119). The example calls for using the OpenScreen function followed by the OpenWindow function. Redefining window.Screen to point to the customscreen and window.Type toCUSTOMSCREEN is required before calling OpenWindow. The call to OpenWindow fails when window.Type is set to CUSTOMSCREEN. If window.Type is left set to WBENCHSCREEN then the customscreen is opened over the window but without any way to close the window. It dosen't appear to be failing due to insufficient memory (~600K available before running the program).

Question: Does anyone know how from within C to find the directory that a program was run from.. I don't mean the currect shell directory.. I want to find the directory where the program actually exists on the disk... Like if I had a file in my C directory I would want the program to get DH0:C even if I was in DH0:Source when I ran the program.. Any help would be appreciated.

It's easy under 2.0: GetProgramDir() returns a lock on the directory, or references things via PROGDIR:. Under 1.3, it's harder. You have to try to second-guess the shell (search the path, etc), and that doesn't help if the command-line specified a directory. -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.cbm.commodore.com BIX: rjesup Common phrase heard at Amiga Devcon '89: "It's in there!"

The standard Commdore Shell (and CLI) don't, and most other shells don't (though perhaps one or two do). If the startup code can't see the shell command-line, it can't use it. I'm fairly sure this isn't tightly specified in ANSI, I suspect it's merely listed as "command name", with no reference to paths, aliases, etc, which are all system-dependant. -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.cbm.commodore.com BIX: rjesup Common phrase heard at Amiga Devcon '89: "It's in there!"
