Hi,
I'm confused about how to make use the HOST function in SQL/FORM 3.0. Is it
possible I can tell the result executed by HOST. For example, I want to check
whether some file exists and write:
:system.message_level := 25;
.......
HOST('ls file', NO_SCREEN);
IF ERROR_CODE <> 0 THEN
END IF;
Also if I write my own program which returns 0 or -1 to represent success and failure and executed by HOST function, is it possible I can tell the result according to the value returned by my program. If yes, how can I do?
Thanks for your opinions!
