Purpose |
Transfer program execution out of a block structure. |
|
Syntax |
EXIT FASTPROC ' FastProc / End FastProc EXIT FOR ' For / Next Loop EXIT FUNCTION ' Function / End Function EXIT IF ' If / End If EXIT DO ' Do / Loop or While / Wend EXIT LOOP ' Do / Loop or While / Wend EXIT MACRO ' Macro / End Macro EXIT METHOD ' Method / End Method EXIT PROPERTY ' Property / End Property EXIT SELECT ' Select / End Select EXIT SUB ' Sub / End Sub EXIT TRY ' Try / End Try EXIT [,ITERATE] ' Exit one loop and immediately iterate another EXIT [,EXIT...] ' The nearest enclosing block structure |
|
Remarks |
The EXIT statement allows you to leave a code section block immediately. Using EXIT by itself will leave the most recently executed structure, but not an outer block. EXIT, EXIT will leave two block structures, and EXIT, EXIT, EXIT will leave three levels. For example: FOR ix = 1 TO 10 DO UNTIL x > 10 EXIT FOR' will exit from the DO LOOP LOOP NEXT EXIT is preferred over GOTO for this purpose. If you want to exit a structure other than the one most recently executed, you may include the type of structure, or you can use multiple EXIT's. The following two examples are functionally identical: FOR ix = 1 TO 10 DO UNTIL x > 10 EXIT FOR ' will exit DO and FOR NEXT loop LOOP NEXT
FOR ix = 1 TO 10 DO UNTIL x > 10 EXIT, EXIT ' will exit DO and FOR NEXT loop LOOP NEXT You can also exit one loop and immediately iterate another: FOR x = 1 TO 10 DO EXIT, ITERATE LOOP NEXT |
