2. STATICS f(len).
3. STATICS: BEGIN OF rec,
END OF rec.
4. STATICS: BEGIN OF itab OCCURS n,
END OF itab.
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
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.
