Hi Mehmet,


The innerloop inl0500 is written by the mkinl program to innerc.c, so I 
would guess that the declaration written to that file differs from your 
header in innerh.h.

First, check that you entered the calling arguments in the right place 
in mkinl_declarations - I think it says in a short comment somewhere 
that for each routine we remove the arguments and variables not used, 
and then create the declaration in the order they are listed. You should 
also be able to check simply by typing 'make innerc.c' and then search 
for inl0500.

Cheers,

Erik
