This one is quite long... I have tried to do it by this way but it seems to have a problem. That's why I try to find another solution...

Hello all! I have change of system: from linux, I am on a Unix workstation and when I compile program which used to work under linux, the following message appears: "Internal compiler error in 'emit_library_call_value', at calls.c:31" What does it mean? thanks a lot for your help, Nathalie ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

On my system if I type I think you're talking about gmp, not gpm (typed correctly 1 and false 3 times ;-). GMP (GNU Multi Precision) is a library for arithmetic with arbitrary precision. GPM is a library for text mode mouse handling under Linux (what does it stand for actually?

OTOH, most of the routines in nrpas are fairly short, so it might be easier to translate them to Pascal than to link the C routines.

>it contains beta.pas (beta function), betai.pas (incomplete beta function which comes in F test), >and betacf.pas, an auxiliary function needed by betai.pas. What do you want exactly: reference ? I need something called "betadev" for beta deviation. I found it in C language but not in pascal.
