[MITgcm-support] parameter file read

Hello folks,

I have a similar problem running verification/exp4 using checkpoint57k_post.

It runs on a mac (xlf 8.1 compiler, single processor), the text output 
has no errors (!) but shows noise in the topography map instead of a 
clear single bump.
Standard error output looks like this:
1525-088 The NAMELIST READ statement cannot be completed because item 
GMkBackground is not a member of the NAMELIST group parm01.  The program 
will recover by discontinuing further processing of the READ statement.

When I run the same code on linux (compiled with g77 3.3.1) it crashes 
with a similar error:
namelist read: variable not in namelist
I'll try to go back to the checkpoint used in the control run...

Thanks, Dmitri
