Hi,
Now the WRONG subroutine will only execute if none of the three IF statements evalutate FALSE
No, as have been said. If the first condition evalutes TRUE the execution will GOTO correct1 and therefor bypass the GOSUB WRONG statement. Same thing if the second or third condition evalutes TRUE. However, if none of the three conditions evalutes true the GOSUB WRONG will execute. Remember that the way you have your IF statment written it'll issue a GOTO, not GOSUB so make sure that your correct1, 2, 3 routines does not end with a RETURN.

That is neat! Although I do not like using goto statements as they can make the program logic difficult to follow.
I totally agree, GOTOs can lead to some real mess but sometimes it's the easy way.....and there's almost always more than one way to do what one wants.
