I will like suggestions on how to solve this problem.
I made a program that make use of an external binary file of, say, 200k-300k.
That is, the program starts, reads in memory this file,
that is always the same (it does not change between executions) 
and then proceed.
I was wondering if I can use just one file, that is putting somehow the
data inside the executable.

I remember that some years ago, I tried to do something similar with another
compiler. I tried to statically initialize a big array of chars.
In practice I wrote a program that given a file will create a source *.c
that statically initialize an array with the data of the file.
However this approach failed on larger dataset, due to some limitation of
the compiler.
I wonder if djgpp, with its lovely flat model,\r has limitations of this kind.

Another approach that  I'm considering is to append physically the data file at
the end of  the executable and then finding a way to access it directly,
but I do not know if in that case the data will be automatically loaded
somewhere in the memory (where !?) or if I must read it from the disk
peeking toward the end of the "extended" executable file.

Suggestions are all wellcome. I'm quite a good C programmer but also quite new
to djgpp and absolutely ignorant about my 586 asm.

Giovanni.
