Am I missing something? The DIR command confirms the existence of

reference the file.
Try the following exercise with two examples and see what you get.
-- Example 01 (Using a Variable)
SET VAR vTest INTEGER = NULL
SET VAR vTest = (CHKFILE('MainData.all'))
SHOW VAR vTest
-- Example 02 (Without Using a Variable)
IF (CHKFILE('MainData.all')) <> 0 THEN
