A programming question

Recommended Posts

Which programming language are you working with? I suppose modular programming is more tidy, in particular as you can reuse code later and build your own libraries, but you may also need to export labels, there could be linker issues if you by mistake used the same memory areas etc. Personally I've almost exclusively worked with one file projects, plus some external macro inclusions, but a friend of mine who does much larger projects build them from dozens of files.

When you're working on a really, really large project that takes several minutes or even hours to compile it can make sense to split things up if your compiler/linker environment is smart enough to only work on the stuff that changed after the last build.


C64 crossassemblers usually need less than a second to finish their job on modern PCs though, so it pretty much boils down to personal preference.


Personally I prefer having all the stuff I work on in a single file, plus maybe some linked in binaries for music, charsets and the like.

Yup, it's just personal taste; i've written larger projects which are a single source file, smaller ones where large chunks of hand-unrolled code are split off into their own file to make the whole easier to read and so on. What suits you best'll becume obvious over time. =-)

When I was programming on the 64 I tended to use a single monolithic file for assembly. When I programmed my BBS I used a single assembly source (though in retrospect I should have divided it up) along with numerous BASIC parts with heavy documentation for each section and a strict over-arching architectural design. I then had a program which would combine the parts into a single program which I would then compile with Blitz!.


Working on my TI projects now, I have multiple assembly source files: base framework, graphics, sound, main game loop, events, and whatever. Mind you, these projects are much bigger than what I did before, and I can only assume closer to the size professional developers back-in-the-day would have built. It is much easier to open the 4anoid_screens.a99 and page through it than have to search a massive file looking for something.
