	* * * * Namelist READs on IBM/AIX * * * *

Hi Andreas,

I believe there is a simple environment variable change on IBM/AIX systems that
can be used to make the Namelist READs work correctly. An example of the
command to set this environment variable in the c shell is:

	% setenv XLFRTEOPTS namelist=old

This command can be inserted into the users .login file.

IBM has changed the way it formats Namelists in its recent versions of "xlf"
(a.k.a. "f77" in other Unix environments). They provided the environment
variable XLFRTEOPTS as a means to restore the previous behavior. (Don't you
love it!)

We will insert an explanation regarding this environment variable into the file
$FER_DIR/README.AIX for future anonymous ftp users. Thanks for pointing out the
omission.
