Quite right - GPOS andd FPOS were supposed to be in absolute pixels but 
they are also used in relative pixels and in arc sec.  So they cannot be 
treated as "system adverbs" so I fixed inputs and go and even patched 
31DEC07 for this.  A MNJ now on 31DEC07 will fetch the corrected code.
NB - I did not test but I know what was needed (I found FPOS a short 
while ago).

MNJ on 31DEC08 needs to wait until later tonight.

Thanks,
