To create a wrapper for this routine, do the following:
>ED BP OPEN.STANDARD.FILES.TCL
001 * OPEN.STANDARD.FILES.TCL
002 CALL OPEN.STNADARD.FILES
003 STOP
004 END
>BASIC BP OPEN.STANDARD.FILES.TCL
>CATALOG BP OPEN.STANDARD.FILES.TCL
Then you can execute OPEN.STANDARD.FILES.TCL before your list statement. I just noticed that you are have this tagged for "u2netsdk". Are you accessing Epicor using .NET api, or the "cd c:/u2/eclipse" and "uv"?
If you are using the .NET api, then you can call OPEN.STANDARD.FILES directly from the .NET api before your EXECUTE the list statement.
