Hi,
I'm using DosStartSession to launch programs the user wants.  Here's my class:
APIRET Launch::Start(HWND hwnd, PSZ Executable, PSZ Title)
{
sdata.Length = sizeof(sdata);
sdata.Related = 1;
sdata.FgBg = 0;
sdata.TraceOpt = 0;
sdata.PgmTitle = Title;
sdata.PgmName = Executable;
sdata.PgmInputs = (unsigned char *)"RENDER.INI";
sdata.TermQ = NULL;
sdata.Environment = NULL;
sdata.InheritOpt = 1;
sdata.SessionType = 2;
sdata.IconFile = NULL;
sdata.PgmHandle = 0;
sdata.PgmControl = 3;
sdata.InitXPos = 0;
sdata.InitYPos = 0;
sdata.InitXSize = 0;
sdata.InitYSize = 0;
sdata.ObjectBuffer = (unsigned char *)buffer;
sdata.ObjectBuffLen = sizeof((unsigned char *)buffer);
rc = DosStartSession(&sdata,&session,&pid);
         if (rc != 0)
        {
        sprintf((char *) ERRORBUF,"An error occured while trying to
start program.  DosStartSession return error = %u",rc);
        WinMessageBox(HWND_DESKTOP,hwnd, (const unsigned char *)ERRORBUF,
(PSZ)"Rayzor Editor/2  : ERROR",0,MB_OK | MB_CUACRITICAL);
        }
}
Here, if the program (Executable) is a DOS program, the program returns an
error 191 for rc (the ERRORBUF messagebox).  It works find for OS/2
Text-Mode apps.  Oh, and all I plan on doing is launching Text-Mode
sessions (that's what is recommended).
