LINKINK MACROS WITH NCMILL

I AM RUNNING V4R2.3 NCMILL ON A IBM 43P-140. I AM UNABLE TO GET A RETURN OR LINKING MACRO TO WORK WHEN USING THE CONTACT, ONE WAY FUNCTION. THE APPROACH AND RETRACT TAKE EFFECT BUT NOT THE LINKING. I HAVE TRIED THIS AT ANOTHER COMPANY ON A43P-150 AND IT WORKED FINE.
IS THER A PARAM. OR SOME OTHER SOFTWARE THAT MAY BE TURNED OFF?
