Try this... It should work with the standard JAMAPI (I think, at least I
can't remember changing anything in it). It's a little piece of testcode
I wrote to play around with JAM :
}
Program JAMTest;

Uses
  JAM, JAMmb, JAMcrc32;

Var
  JAMMsg     : JAMAPIPTR;
  ToUsername : String[100];
  Position   : LongInt;
  S          : String;
  MsgNo      : LongInt;
  Error      : Boolean;

Function FileLength (Handle:INTEGER) : LongInt;
Var
  Position : LongInt;
Begin
  Position   := JAMMsg^.SeekFile (Handle, 1, 0);
  FileLength := JAMMsg^.SeekFile (Handle, 2, 0);
  JAMMsg^.SeekFile (Handle, 0, Position);
End; { FileLength }

        Begin
