Subject: Launching a Sys16 application from a Orca/C Program
--------

        I am currently trying to write a program in Orca/C that will launch
anan
other program, namely Finder, Wings, ProSel 16, etc.

        The program that I am attempting to write will be a Password protection
type program, that will prompt the user to enter the password.  Once the
correct password has been entered, then my program will launch the REAL program
selector/manager.

        So far, I have successfully written the Password part, but for the life
of me, I can't find any reference in the Orca/C manual, nor the Tool box refs
Vol I, II, regarding launching another application.  The Apple IIgs
_Programmer'
s Intro to the Apple IIgs_ briefly described the procedure, but since
Hodge-Podge didn't have anything to do with it, they didn't provide any exact
codes in C.  (I tried looking the the Tool Ref II, in the Standard File
Operation Tool Set, but that only covers load and save, NOT launch.)

        The only mention of it that even comes to what I want is in the Orca/C
manual, where I am told to use

        System          in the Libraries

        #include <stdlib.h>
        int system(char *command);


        I have tried using

        System("1/system/Finder");


        But to my dismay, it works well under the shell, as an EXE file, but
when I changed the file to a Sys16, then it won't launch Finder.  (I did
remember to turn the debugging option off, when making a Sys16 file.)

        I would be eternally (well, maybe not THAT long :)  ) greatful if
someone could provide me with the EXACT code for launching a SYS16 program
from Orca/C.
