STATICS

Variants

...
END OF rec.
4. STATICS: BEGIN OF itab OCCURS n,
...
END OF itab.

Effect

The STATICS statement is a variation of the DATA statement. It allows you to define variables in a procedure (i.e. a FORM or FUNCTION ) with local visibility, but static validity.

Static validity means that, unlike normal local variables, the life of static variables does not depend on the defining procedure, but on the program at runtime. Static variables are thus not redefined on the stack each time the defining procedure is called, but exist independently of this in the program and keep their value, regardless of calls to the defining procedure.

Like all other data objects , static variables always have a particular data type. Data types and data objects are important components of the ABAP/4 type concept .

Example


DATA RESULT TYPE I.

PERFORM RANDOM CHANGING RESULT.

FORM RANDOM CHANGING P_RESULT TYPE I.
  STATICS L_STATE TYPE I.
  L_STATE = ( L_STATE * 113 + 34 )  MOD 256.
  P_RESULT = L_STATE.
ENDFORM.
