Hello,

I'm a novice in gpc and I hav a lot of problems. Here comes the first one:

unit unit1; { reine testunit fuer gpc } Interface Procedure ClrScr;

Implementation

Procedure ClrScr; Var i : Real; Begin For i := 0 to 25 Do WriteLn; End;

Begin End.

I run gpc under Linux 2.0.30 and had the following output:

voss@crazy_horse:/home/voss/pascal > gpc unit1.pas /usr/lib/crt1.o: In function start': /usr/lib/crt1.o(.text+0x5a): undefined reference to main'

To compile a unit do this: gpc unit1.pas -c The -c option tells gpc to just compile and not to link.

Another problem comes, when I choosed the Type Byte for the variable i.

If you want to define a byte variable do it this way: var JustAByte : __byte__ integer; or even define a 'byte' type (This is what I do) type byte = __byte__ integer; There are many other type 'modifiers' available. I don't have my Linux PC with me here at work but I think the type modifier list is in the 'news' file somewhere in the distribution. Hope this helps! Ken L.
