The [EXIT](EXIT) statement is used to exit certain QBasic procedures.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
> [EXIT](EXIT) {DO|WHILE|FOR|SUB|FUNCTION|SELECT|CASE}
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
* [EXIT](EXIT) leaves any of the following procedures immediately.
|
||
|
|
* [EXIT](EXIT) DO exits a [DO...LOOP](DO...LOOP).
|
||
|
|
* [EXIT](EXIT) WHILE exits a [WHILE...WEND](WHILE...WEND) loop.
|
||
|
|
* [EXIT](EXIT) FOR exits a [FOR...NEXT](FOR...NEXT) counter loop.
|
||
|
|
* [EXIT](EXIT) SUB exits a [SUB](SUB) procedure before it ends. Use before any [GOSUB](GOSUB) procedures using [RETURN](RETURN).
|
||
|
|
* [EXIT](EXIT) FUNCTION exits a [FUNCTION](FUNCTION) procedure before it ends. The value passed by the function's name should be defined.
|
||
|
|
* [EXIT](EXIT) SELECT exits a [SELECT CASE](SELECT-CASE) block.
|
||
|
|
* [EXIT](EXIT) CASE does the same as EXIT SELECT unless when used in a **SELECT EVERYCASE** block; in such case, execution proceeds to the next CASE evaluation.
|
||
|
|
* EXIT statements normally use an [IF...THEN](IF...THEN) statement to evaluate a program condition that would require the EXIT.
|
||
|
|
* To exit a program and allow the last program screen to be displayed with the message "Press any key to continue...", use [END](END).

|
* To exit the program immediately, use [SYSTEM](SYSTEM).
