EXIT IF
(Exit from
a loop depending on a test)
EXIT IF expression[,n] As you can see from the previous EXIT instruction, it's often necessary to terminate a loop depending on the outcome of a specific set of conditions. This is simplified using a special EXIT IF command. expression consists of a series of tests in the standard AMOS format. The EXIT will only be performed if the result evaluates to -1 (true). The n parameter allows you to quit from several loops at the same time. If it's omitted then only the current loop will be aborted. Example:
While L=O Z=O
Do
Z=Z+1 For X=O To 100 Exit If Z=1 0,2 : Rem Exits two Loops, DO and FOR Next X Loop Exit 1 : Rem Terminates While •••Wend Wend
