Greetings James..

Although John may some ideas for you to implement on how to utilize
DJGPP with the RHIDE visual front end you need to realize that modular
programming involves a design approach that uses the concept of:

* Header file
* Client file
* Implementation file(s)

I can certainly see if you stuck _all_ your code in one file how this
could end up being a nightmare.. Part of the 'top down approach' is to
break the Big problem into smaller problems which lends itself to this
type of design philosophy. Further, C / C++ lends itself to this type
of design VERY nicely since its modular.. As John mentions, in the
above style of design, function(s) each exist to be called by the
client program which, itself is usually quite small.. The various
'functions' exist as implementation file(s) that can be modified
individually thus modifying or debugging individual 'modules' doesn't
become such a nightmare.. Additionally, modern day compilers will ONLY
compile the implementation files (functions) that have changed while
NOT bothering with those that haven't changed thus potentially
reducing your compilation time tremendously..

Cheers,
Gary

Coincidentally, this design approach is typically taught in the class
room of most colleges.
