Re: Exit/End Sub
no - sorry - end sub etc takes you back to where the sub was called. What you can do is set a flag if you want to take alternative actions on return
e.g. I have a search sub-routine which produces a result of 0 is no match found, 1 if a match found etc - the search sub is called and the flag% parameter is passed with a value of 0.
If the flag comes back to the calling routine as 0 then action (a) is taken, if 1 (found) then action (b)
If I remember correctly, a gosub has to be in the same module/subroutine for it to work and not outside it.
No doubt someone will correct me if I'm wrong!!
