Q:  I have an OBJ file that has several assembler routines compiled into it.  I wouldn't want to have to rewrite them.  Is there a way to use them in a Delphi app?

A:  You don't indicate if these return values or not.  In Pascal this matters.

If they don't, include the following near the front of your code:

 Procedure TurnOn;  External;
 Procedure TurnOff; External;

If they return values, use:

  Function TurnOn: Integer; External;
  Function TurnOff: Integer; External;

Replace Integer with whatever datatype they return.

In either case follow that with:

  {$L filename.obj}

to link in the obj file.
