Passing a variable to output message on NonStop

[smitty3501]

Trying to assign then pass a variable when I generate an alert.  

NUMERIC mt10r50pos[0] := 0

IF @B24POS.RESPCODE = "050"
SET mt10r50pos := @b24pos.trancnt

END_IF

                            had my base24 tester   send 1 decline  so it would trrigger the below

IF mt10r50pos > 0
SET pMsg := "MasterCard [9810] POS TRANCODE 10 [Normal purchase]:"
SET aMsg := "DECLINE CODE 050 Value of @mt10r50pos@ EXCEEDS THRESHOLD OF 0"
SET crit := "Critical Event:"
LOG EMS 0301 PRIORITY CRITICAL EVENTNUMBER 6099 COLLECTOR $CPRG IMMEDIATELY

                      here is output from collector .  I should have said "1"  for this test and not @MT10R50POS@@

10:47:00 06MAR23 062,02,2096 B24POS: CRITICAL EVENT:
MASTERCARD [9810] POS TRANCODE 10 [NORMAL PURCHASE]:
DECLINE CODE 050 VALUE OF @MT10R50POS@@ EXCEEDS THRESHOLD OF 0

When you want Variables inserted into a string you need to use the SUBST command.

Try changing

SET aMsg := "DECLINE CODE 050 Value of @mt10r50pos@ EXCEEDS THRESHOLD OF 0"

to 

SET aMsg := Subst ("DECLINE CODE 050 Value of @mt10r50pos@ EXCEEDS THRESHOLD OF 0")

Just to add to Leon's response, if you're after more information on the SET function, you can find additional details on this page in the product guide!
