| condition = any valid conditional statement |
|
The WHILE/WEND loop is used when you wish to execute a series of commands multiple times based on whether a condition is true or not. This is similar to the REPEAT/UNTIL loop, except the condition checking is at the beginning of the loop, instead of at the end. Usually you'll use WHILE/WEND when you aren't sure whether or not the looped commands will even need to be executed once, since you can actually stop the loop before any commands are executed if the condition check fails. If you need to execute the commands in the loop at least once before checking a condition, use REPEAT/UNTIL. See example.
