According to Alessandro Graizzaro:

I'm new with gnu pascal, and with Linux too. I decided to try it, because I need a lot of memory for my computations.

1. Can anoybody of tell me how can I define DOUBLE type ?

"Real" *is* what you know as "Double" from Borland Pascal. Borland's 6-byte software real does not exist with GNU; "Single" is "__short__ Real", "Extended" is "__long__ Real".

Known bug: you cannot writeln __short__ or __long__ Reals at the moment, but have to convert them to "ordinary" Reals, first.

2. Is it possible to use the USES clause as in TP ?

Yes. See README.TURBO for details (2.6.3 version) or the "From Borland to GNU Pascal" section of the INFO documentation of the 2.7.2-beta version.

Where to find something like CRT, GRAPH ...?

Graph is worked on for the DOS platform. For Linux, you can use the VGAlib C library with "external", "C", and "asmname" Procedures and Functions. CRT does not yet exist -- we are looking for somebody to implement it. However, have a look at BO5 (in the turbo-alpha directory). Its "Events" and "Displays" Units provide important parts of CRT's functionality.

Hope this helps,

Peter
