Sorry for confusion, my email wasn't clear... old fpc version, that I have to use because of availability of various units...Free Pascal Compiler version 2.2.2 [2008/08/03] for i386
this is jim.pp--- unit jim; interface function fna:string; function fnb:string; implementation function fna:string; begin fna:='jim'; end; function fnb:string; begin fnb:=fna; end; end. this is fred.pp--- uses jim; function fna:string; begin fna:='fred'; end; begin writeln(fnb); end. This writeln gives jim, ie the version in jim - I'd like it to be fred & thought that it would! What can I do please, to _force_ fnb to use the fred version of fna?

If so, then this isn't possible.
