[MITgcm-support] TAMC bug?

[Patrick Heimbach]

Daniel,

this is an old TAMC (but not TAF) problem which Ralf chose not to fix.
Indeed, TAMC does not unerdstand blanks in PARAMETER statements
of the sort you describe
(it does understand blanks in other assignments).
I had thought I had removed all the _d assignments in
PARAMETER statements, but it seems I've overlooked a few.
Thanks for the heads-up, I'll commit them soon.

Cheers
-p.
