How to check if label exists?

[MikeBaas]

I'm in a situation where I'd like to do:

goto %label

and %label is user-input. So it could not exist. Is there a way to validate %label and make sure it is valid? Or should I just catch the error?

You could probably make this more robust. The file in question has the label (actually a subroutine)

:makevbs [file]

v:\> ffind /q /t":fakevbs" sv.btm & echo %_?
2

v:\> ffind /q /t":makevbs" sv.btm & echo %_?
0

And then there's

IF ISLABEL

Wow...well, it's ISLABEL then! Thanks! :-)
