:-)                    
Ok, thanks for the advice. I'll do this.

Ok, after making a cool batch file that copies some critical 
files over to my ramdrive things are sped up :). My compile time
is now under 20 sec as opposed to over 60 sec before.

Ok, I'll try copying over those files you suggested as well.

Sounds good. As soon as I can get all Allegro commands to run under 
win95, I'll do that switch.

I'm sorry. I just meant compiler optimization.  
The troubles I had with the .dat files:
A) I can't load a BITMAP into memory from a .dat file because I am unsure
of the code...
B) I am unsure of whether the .dat file loads itself fully into memory.
Since my game is a slow paced RPG, I have no need for all the BITMAPs
to be in the memory, and there are ALOT of BITMAPs appx 1000+. I have 
other devious uses for the memory...

So anyone who has any information on .dat files, please tell me.
I'm stuck doing things like making graphics and such until I get this
crucial information to continue coding...

Excellent! You and everyone else on this newsgroup are of incredible 
help. I'm going to go get my code to crash now :)
