Sounds like we need more and more an option to eliminate that 4byte 
package for special defines, Rob. Even if it's 2bytes, that saves some of us 
100's of megs of memory. How about a way to "include" the included file that 
loads these big files? If the "include as" syntax knows more about the 
contents of the vars and procedures in that file,, can the var tags be reduced 
to 2 bytes? 

Alternatively, has anyone consider using objects to point into allocated byte 
arrays in memory for these huge user blocks? Personally, i don't know what 
would happen if you asked windoze for physical memory that wasn't there,, 
or will win32lib deal with that transparently, calling a virtual allocate(),
etc?
