FB_OPTION_GOSUB

Intrinsic define (macro value) set by the compiler

Syntax

__FB_OPTION_GOSUB__

Description

Indicates how GoSub and Return will be handled at compile time. If the option is set (-1) then GoSub is allowed and Return is recognized as return-from-gosub only. If the option is not set (0) then GoSub is not allowed and Return is recognized as return-from-procedure only.

This macro value can be changed at compile time. Option Gosub will set the option (enable gosub support) and Option Nogosub will clear the option (disable gosub support).

__FB_OPTION_GOSUB__ returns zero (0) if the option has not been set. Returns non-zero (-1) if the option has been set.

Remarks
