The EXIT statement is used to exit certain QBasic procedures.
Contents
Syntax
- EXIT {DO|WHILE|FOR|SUB|FUNCTION|SELECT|CASE}
Description
- EXIT leaves any of the following procedures immediately.
- EXIT DO exits a DO...LOOP.
- EXIT WHILE exits a WHILE...WEND loop.
- EXIT FOR exits a FOR...NEXT counter loop.
- EXIT SUB exits a SUB procedure before it ends. Use before any GOSUB procedures using RETURN.
- EXIT FUNCTION exits a FUNCTION procedure before it ends. The value passed by the function's name should be defined.
- EXIT SELECT exits a SELECT CASE block.
- 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 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.
- To exit the program immediately, use SYSTEM.
Availability
- EXIT SELECT/CASE available with v1.5.
- All other variants available in all versions of QB64.
