|
|
* Only one conditional evaluation can be made at the start or the end of a [DO...LOOP](DO...LOOP).
|
||
|
|
* DO UNTIL evaluates a condition before and inside of the loop. The loop may not run at all.
|
||
|
|
* LOOP UNTIL evaluates a condition inside of the loop. It has to loop once.
|
||
|
|
* Skips the loop or loops until an evaluation becomes True.
