WHILE - VARY
Obsolete Syntax
WHILE ... VARY dobj FROM dobj1 NEXT dobj2 [RANGE range]
[VARY ...].
[statement_block]
ENDWHILE.
Effect
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.
Note
Instead of the addition VARY, the statement
ASSIGN should be used in the loop with the addition INCREMENT.
