We are using Progress Version 9.1D09 and looking at developing a trigger program using handle to accomplish this task. But, we are encountering a SYSTEM ERROR: Memory violation. (49).
Attached is the below code for your reference.
{mfdtitle.i}
DEF VAR lc_nbr like so_nbr no-undo.
DEFINE VARIABLE h1 AS HANDLE NO-UNDO.
DEFINE VARIABLE h2 AS HANDLE NO-UNDO.
def var lg_flag as Logical no-undo.

DO:
ASSIGN h2 = self.
DO WHILE VALID-HANDLE(h2):
IF h2:name = "so_nbr" THEN
DO:
ASSIGN lc_nbr = self:screen-value.
ASSIGN h2 = h2:NEXT-SIBLING.
END.
END.
