[ferret_users] Limit on number of variables has been reached

[Ogunro Oluwaseun <ogunrooluwaseun@xxxxxxxxx>]

Hello All,

I am working with;
..............................................................
NOAA/PMEL TMAP
 	FERRET v6.82
 	Linux 2.6.18-308.1.1.el5 64-bit - 08/03/12
 	 9-Jul-13 14:10
.................................................................

Can anyone help me out with this error message;

.............................................................................................
**TMAP ERR: limit on number of variables has been reached
             MAX=        2000
             Data set: ./October.h.0033-10.nc
..............................................................................................

I was working with monthly ncdf model outputs. I have the 12 (Jan to
Dec) netcdf files in a jnl file. So, i was trying to do some
calculations and make some plots on ferret.
The error message came up when the file got to October (3 months left).

Is it possible to increase the number of variable, or what are
possible ways to get through this error on this version of ferret.
I will appreciate solutions that can make me work with all my
variables or select some of them for my calculations (in case i can
not work with all variables)
I couldn't find anything helpful in the ferret_users mail archives.

Regards
Ogunro
