Has anyone here ever used Free Pascal or GNU Pascal?

[Learning Linux 2011]

Greetings,

I am new to Linux and Linux programming.

I used to program Turbo Pascal in DOS a long time ago. I have some old programs that I thought I could copy and paste into Linux to get started.

I downloaded both Free Pascal and GNU Pascal, opened a terminal and tried to compile this Pascal program (one of the first programs I ever created) :


{This program reads in an integer and cubes it}

Program cube;
var n : integer;

Begin
writeln(' Please enter an integer and this program will cube it');
readln (n);
writeln( 'The cube of ' ,n, ' is ' , n * sqr(n), '.');
readln;
End.


I saved the file as Cube.pas in my Home directory.

Can anyone tell me how to get started using Linux? Do I need to do something else?
This program works in DOS using Turbo Pascal 7.

with gnu pascal

gpc Cube.pas -o cube
it will produce binary file named cube

Thanks, that worked.

Now how do I actually run the file? Lol, sorry, I'm new to this.

i admit, i forgot to mention that obvious 2nd step

./cube
