Is EOF an implied RETURN?

vefatica · Jun 26, 2020

I occasionally run into this (when I neglect to end a subroutine with RETURN). EOF works just as well. Is that WAD?

Code:

v:\> type impliedreturn.btm
echo 1
gosub foo
echo 3
quit

:foo
echo 2

v:\> impliedreturn.btm
1
2
3

WAD - but relying on it is sloppy and liable to break as soon as you add anything to the file.

Thanks. I wasn't planning on relying on it. Just curious.

To add: this also works same way in CMD. To return from a subroutine call you have to reach the end of file. One way or another.
