While

Synopsis

while ( expression ) { }

Description

While loops test the expression and if true, continuously executes the code provided until the expression is no longer true. Unlike repeat..until, while loops will not execute at all if the expression evaluates to false.

Example

set %Test 1

while %Test < 10
{
;Code between these brackets, gets executed, while %Test is smaller than 10
;When its 10, it wont jump back to first bracket.
set %Test %Test + 1
}
display ok %Test $
halt

%Test holds the value of 10. Notice the condition "%Test < 10". If that becomes true, the script won't jump back to the while loop start, but continues normally.

Flow Control

• Flow control commands allow scripts to make decisions based on the evaluation of boolean expressions.

break	Jumps to first statement outside of loop
call	Transfers execution to another script file
continue	Jumps execution of a loop to next iteration
exit	Exits a called script
for	Creates a counting loop
gosub	Transfers execution to the matching sub
goto	Jumps to another part of the script given by a label
halt	Stops the script
if	Executes code based on the evaluation of an expression
pause	Temporarily stops the execution of the current script
repeat..until	Creates a loop that checks condition after execution
return	Returns from a sub
stop	Ends the script
while	Creates a loop that checks condition before execution
