WHILE and WEND
The WHILE
directive starts a sequence of instructions or directives that are to be assembled repeatedly. The sequence is terminated with a WEND
directive.
Syntax
WHILE logical-expression
code
WEND
where:
logical-expression
is an expression that can evaluate to either
{TRUE}
or{FALSE}
.
Usage
Use the WHILE
directive, together with
the WEND
directive, to assemble a sequence
of instructions a number of times. The number of repetitions can
be zero.
You can use IF...ENDIF
conditions within WHILE...WEND
loops.
WHILE...WEND
loops can be nested.
Example
GBLA count ; declare local variable count SETA 1 ; you are not restricted to WHILE count <= 4 ; such simple conditions count SETA count+1 ; In this case, this code is ; code ; executed four times ; code ; WEND
