Exit or Return codes for LBB console programs?
« Thread started on: Jul 14th, 2017, 01:04am » |
|
Is it possible to exit a compiled LBB program with a return code (equivalent to %ERRORLEVEL% in WinNT batch script)?

I believe that currently the only way to do that in LBB is to invoke a BBC BASIC statement:
Code:
If you compile this as a console application it sets %ERRORLEVEL% to the entered value:
Code: input "Enter required return code: "; returncode
!QUIT returncode

Yes, that is exactly what I was looking for. Without delving into some BBC Basic docs (which I've always meant to do), I will assume that QUIT is equivalent to END? No need to reply, unless I'm wrong. ^_^
Oh, and thanks again.
Console apps, return codes, small executables, expanded arrays, OOP (which I'm still getting my head around)... a whole litany of reasons I enjoy using your little utility.

It's rather more 'final', in that !QUIT immediately and unconditionally terminates the application, whereas the behavior of END depends on whether there is a NOMAINWIN statement and whether your program was compiled or run from the IDE.
