Effect
Syntax check for screen
The screen description is taken from the field string h and the internal tables f , e and m . The field string h (screen header) should correspond to the structure D020S , the internal table f (field list) to the structure D021S , the internal table e (flow logic) to the structure D022S and the internal table m (matchcode information) to the structure D023S .
Example
DATA: DHEAD LIKE D020S, "screen header
DFIELDS LIKE D021S OCCURS 20, "field list
DFLOWL LIKE D022S OCCURS 20, "flow logic
MCINFO LIKE D023S OCCURS 20. "matchcode information
If a syntax error is detected during the check, the fields f1 , f2 and f3 are filled as follows:
- f1 contains the error message text
- f2 contains the screen line where the error occurred
- f3 contains the incorrect word in the screen
