SYNTAX-CHECK FOR DYNPRO  Syntax Diagram

This statement is for internal use only.
It must not be used in application programs.


Syntax

SYNTAX-CHECK FOR DYNPRO h f e m ...MESSAGE f1 ...LINE f2
                                ...WORD f3.


Parts marked with " ..." are interchangeable

Extras:

1. ... OFFSET f4

2. ... TRACE-TABLE itab1

3. ... MESSAGE-ID f5

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. For f, e, and m you can specify standard tables without secondary keys.

Example

DATA: DHEAD    TYPE D020S,                   "screen header
      DFIELDS  TYPE TABLE OF D021S,          "field list
      DFLOWL   TYPE TABLE OF D022S,          "flow logic
      MCINFO   TYPE TABLE OF D023S.          "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.


System Fields

sy-subrc Meaning
0 The screen contains no syntax errors.
4 The screen contains syntax errors.

Addition 1

... OFFSET f4

Effect

When a syntax error occurs, the position of the incorrect word in the incorrect line is stored in this field.

Addition 2

... TRACE-TABLE itab1

Effect

Any trace output is stored in this table. Trace output is automatically switched on when you specify this addition. You can specify a standard table without secondary keys for itab1.

Addition 3

... MESSAGE-ID f5

Effect

If a syntax error occurs, the key of the corresponding error message is returned in field f5. This key has the same structure as the key of table TRMSG.
