Other versions: 7.31 | 7.40 | 7.54
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 similarly 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 a loop with the addition INCREMENT
.
