Yes.  Try this instead:

--------------------------------------------------------
h dftactgrp(*no) bnddir('QILE')

d Cos             pr                  extproc('CEESDCOS')
d  Parm1                         8f
d  Parm2                         8f
d  FeedBack                     12

d Parm            s              8f   inz
d Result          s              8f   inz
d FB              s             12a

c                   callp     Cos(Parm:Result:FB)
c     Result        dsply

c                   eval      *inlr = *On
