The UNTIL condition is used in DO...LOOP exit verifications.
Syntax
- DO [UNTIL] evaluation
- .
- .
- .
- LOOP UNTIL evaluation
- Only one conditional evaluation can be made at the start or the end of a 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.
| Symbol | Condition | Example Usage |
|---|---|---|
| = | Equal | IF a = b THEN |
| <> | NOT equal | IF a <> b THEN |
| < | Less than | IF a < b THEN |
| > | Greater than | IF a > b THEN |
| <= | Less than or equal | IF a <= b THEN |
| >= | Greater than or equal | IF a >= b THEN |
