Hi Alberto,
Make sure you null terminate your command. This works OK for me:-
identification division.
program-id. Program1.
environment division.
configuration section.
data division.
working-storage section.
procedure division.
call "system" using z"dir c:\|more"
goback.
You can also use the X"91" Function 35 call to do this:-
documentation.microfocus.com/.../index.jsp;cp=5_5_3_9_30_6
or go to a Windows API (CreateProcess).
Regards
David
