Math Bindable API

Hello all!

If I have to use the Math Bindable API's CEESSCOS and CEESSSIN as a
procedure that returns a value, do I have to pass mandatory as well as
optional parameter all the time.


h dftactgrp(*no) actgrp(*new) bnddir('QILE')

d Sin             pr             4f   extproc('CEESDSIN')
d  Parm1                         4f
 *
d Cos             pr             4f   extproc('CEESDCOS')
d  Parm2                         4f

d x               s              4f   inz
d LatRad1         s              4f   inz
d LatRad2         s              4f   inz

c                   eval      x = (Sin(LatRad1) * Sin(LatRad2)) +
c                                 (Cos(LatRad1) * Cos(LatRad2))


OR

do I have to specify

d Sin             pr             4f   extproc('CEESSSIN')
d  Parm1                         4f
d  FeedBack1                    12    options(*omit)
 *
d Cos             pr             4f   extproc('CEESSCOS')
d  Parm2                         4f
d  FeedBack2                    12         options(*omit)

d x               s              4f   inz
d LatRad1         s              4f   inz
d LatRad2         s              4f   inz

c                   eval      x = (Sin(LatRad1:*omit) * Sin(LatRad2:*omit)) +
c                                 (Cos(LatRad1:*omit) * Cos(LatRad2:*omit))


When I used the first approach the program worked fine for the first time.
But, everytime I compile and then call the program, the program bombs with the 
foll. errors
     Pointer not set for location referenced.
     Unexpected user error occurred in CEESSSIN.

Strangely enough, the program seems to work in debug mode!!

What am I doing wrong?
