Most of my programming is for business use.  A lot of the time the user 
will make an entry and depending on what they enter the program will 
continue or jump to a totally different area.  While it may be possible 
to do with a couple of different entries to eliminate the jumps I don't 
think it makes the code any more readable, and after that it is almost 
impossible.  I did manage something like this in C using a case 
statement to determine what function to call next but Business Basic 
does not have this ability.
