GSAK (Geocaching Swiss Army Knife)
Use this command to repeat a sequence of statements until a certain condidtion exists. Basically it is very similar to the While command, the main difference is that your loop is *always* executed at least once. While still has it's uses but many programmers find the repeat/until construct more intuitive - and easier to follow in many circimstances.
Repeat statements can be nested, but every Repeat statement must have a matching Until statement. Use BreakRepeat to break out of the Repeat loop
Use Until <expression> to complete the loop. The expression used must return a Boolean true or false value.
