Below is an example of using the MS OS/2 API function DosExecPgm. This
program must be compiled with Microsoft BASIC Compiler Versions 6.00
or 6.00b for MS OS/2 or Microsoft BASIC Professional Development
System (PDS) Version 7.00 for MS OS/2.

The following is the example code:

'The definitions are taken from BSEDOSPC.BI
TYPE ResultCodes
     codeterminate as integer
     coderesult as integer
END TYPE
DECLARE FUNCTION DosExecPgm%(_
        BYVAL p1S AS INTEGER,_
        BYVAL p1o AS INTEGER,_
        BYVAL p2  AS INTEGER,_
        BYVAL p3  AS INTEGER,_
        BYVAL p4s AS INTEGER,_
        BYVAL p4o AS INTEGER,_
        BYVAL p5s AS INTEGER,_
        BYVAL p5o AS INTEGER,_
        SEG   p6  AS ResultCodes,_
        BYVAL p7s AS INTEGER,_
        BYVAL p7o AS INTEGER)
DEFINT A-Z
DIM results as ResultCodes

INPUT "Enter NAME of EXE file (with .EXE) to execute: "; fln$
fln$ = fln$ + chr$(0)
buffer$=space$(255)+chr$(0)
bufferlen = len(buffer$)
AsyncTraceFlags = 1  'Execute Asynchronously to the parent
ArgPointer$=chr$(0)
EnvPointer$=chr$(0)
x% = DosExecPgm(varseg(buffer$),sadd(buffer$),_
                bufferlen,AsyncTraceFlags,_
                varseg(ArgPointer$),sadd(ArgPointer$),_
                varseg(EnvPointer$),sadd(EnvPointer$),_
                results, varseg(fln$),sadd(fln$))
PRINT "ExecPgm Error CODE : ";x%
SLEEP(5)
PRINT "This Parent is Complete"
