Howdy Ed,
"Binding" is the word they use to indicate QB is creating what's needed to
execute the source code in memory.  Part of that is indexing the source code 
to the executable code so single stepping  will display the proper line.
Some portion of the code you keyed in is doing something completely 
unexpected by QuickBasic.  Take a scan through it and REM out questionable 
parts, save your work as readable text, then try running it again.  If that 
runs, then start removing the REM's until it balks again.
As a tip, when typing in code like this it's a good idea to save and try 
running it every 25 lines or so.  I strongly recommend always saving your 
code as "readable".
