• VARY FROM NEXT WHILE - obsolete • RANGE WHILE - obsolete
WHILE, VARY Short Reference
ABAP_SYNTAX_OBS WHILE ... VARY dobj FROM dobj1 NEXT dobj2 $[RANGE range$] $[VARY ...$]. $[statement_block$] ENDWHILE.
What does it do? The addition VARY and its addition RANGE have exactly the same effect on a WHILE loop as the other obsolete additions VARYING and RANGE of the statement DO. The addition VARY can be used more than once in a WHILE statement.
Latest notes:
The way the addition VARY works depends on the internal structure of the working memory, which itself can be affected by alignment gaps.
Instead of the addition VARY, the statement ASSIGN should be used in the loop with the addition INCREMENT. ABAP_HINT_END
