Dear all, I would like to write a program that must work in MS DOS with an input from file and output to another file, also I would like to compile the same program in linux with the same premises (input and output to files).

Another doubt, is it possible to use GSL or Newmat as a library in FPC Lazarus to compile those programs?

Thanks a lot,

There should be no problem with this.

I don't know if there are any existing header translations of these libraries to FPC/Delhi that you could use. If not, you or someone else will first have to make one before they can be used.
