I have no problems compiling and running under Borland, but I do not have dos based machines at my disposal and would like to compile under either gpc or xlp.

Xlp? Is that something we should know about?

Is there some library i need to tell it to link?

GNU Pascal has no built-in Assign procedure. You can use the "BPCompat" Unit from the "contrib" subdirectory of the GPC source distribution (same as the "System" Unit from the new BPCompat package). Alternatively you can write it yourself using Extended Pascal's "bind" mechanism:

Type WrkString = String ( 255 );

Procedure Assign ( Var T: Text; Name: WrkString );

Var B: BindingType;

begin (* Assign *) unbind ( T ); B:= binding ( T ); B.Name:= Name; bind ( T, B ); B:= binding ( T ); end (* Assign *);

Hope this helps,
