JG=> Could someone PLEASE explain  exactly how seperate modules work?   I'm
    trying to break up my program into 2 modules, so that it will be in the
    right  size  for  the  compiler,  but  it  isn't  working..  Can I call
    subroutines from the 1st  module from within a  sub from the 2nd?   And
    how do  I have  variables that  will work  in both  modules and in both
    modules's subroutines?  I've found that DIM SHARED doesn't work  across
    different modules..  Can somebody help me??

1. You may put your root  program (the one outside all the  subs/functions)
    in only one .BAS file
2. All the  subs/functions that SHARE  variables must be  in the same  .BAS
    file.
3. For a  module, to know  what are the  external (other modules)  subs and
    functions, you must include a DECLARE SUB/FUNCTION at the beginning  of
    your program, before any executable statement.
4.  You  compile  each  module  (.BAS  file) separately with BC. No special
    option is needed.
5. You link each object file together  with a '+' sign on the LINK  command
    line. Ex: LINK PROGMAIN+PROG1+PROG2; [Enter]. You should put the module
    that contains the root program first.
