When I compile this code:
program radar;
uses crt, graph;
var DriverVar, ModeVar : integer;
begin DriverVar := Detect; ModeVar := 2; InitGraph(DriverVar, ModeVar,''); SetColor(4); LineTo(100,100); end.
I get an error message:

1) Is 'Detect' integer? I can't tell from here.
2) Shouldn't InitGraph receive a path? See "PathToDriver" in http://www.freepascal.org/docs-html/rtl/graph/initgraph.html

No, the reason is different. This code also doesn't work:
program radar;
uses crt, graph;
var DriverVar, ModeVar : integer;
begin DriverVar := 0; ModeVar := 2; end.
Same error:

Hello.
Did you read the error message yet? It says, there's no unit graph. there is, however a package called graph, which is not associated with what you wnat from the compiler. However, I looked into things:
martti@deepthought:~$ pacman -Ql fpc | grep graph fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/Package.fpc fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ggigraph.o fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ggigraph.ppu fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/libpggigraph.a fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/libpptccrt.a fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/libpptcgraph.a fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ptccrt.o fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ptccrt.ppu fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ptcgraph.o fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ptcgraph.ppu
After a minimum of testing I found that pascal units are stored as ".ppu" files. Then I tried this: "uses ptccrt, ptcgraph" - and it compiled. My pascal knowledge is very limited, and the first program pops away just after it is started... maybe you could wait for X keyboard events or add an endless loop.
cheers! mar77i

Thanks! I first tried this method in the IDE, and he gave the same error. However, from the console it works! Is this a bug? And more. Writing 'ptcgraph' instead of 'graph' breaks backward compatibility with Turbo Pascal.

Because graph does not exist in x86_64. Anyway if you want to use graph in i686 you need svgalib (from AUR), and who knows if works in these days...

Wasn't there an SDL driver for graph?

The sdlgraph, is only available in i686. There is a ggigraph, but who knos if libggi builds/works. Also there is a ptcgraph thats seems to works.
