| WHILE...WEND Statement Details |
|
| Syntax |
| WHILE condition |
| [statements] |
| WEND |
| |
| If the condition is true (that is, if it does not equal zero), then any |
| intervening statements are executed until the WEND statement is encountered. |
| BASIC then returns to the WHILE statement and checks condition. If it is |
| still true, the process is repeated. If it is not true (or if it equals |
| zero), execution resumes with the statement following the WEND statement. |
| |
| Note: QuickBASIC's DO...LOOP statement provides a more powerful and |
| flexible loop control structure. |
| |
| WHILE...WEND loops may be nested to any level. Each WEND matches the |
| most recent WHILE. An unmatched WHILE statement causes an error message |
| that reads "WHILE without WEND." An unmatched WEND statement causes an |
| error message that reads "WEND without WHILE." |
| |
| Note: Do not branch into the body of a WHILE...WEND loop without |
| executing the WHILE. This may cause run-time errors or program |
| problems that are difficult to locate. |
