TMAP ERR: limit on number of variables

[Choo Heng Kek <hengkek@xxxxxxxxxx>]

Hello all

I'm using ferret 5.40 on Solaris 8.  Has anyone managed a workaround for
the problem with the following error message?
---------------
**TMAP ERR: limit on number of variables has been reached
             MAX= 500
             Data set: ./MAP28.nc
---------------

I was trying to group 38 netCDF files together into one file, using a
.jnl script like the one below:

...[snip]...
use MAP01.nc
save/file=all.nc Wxx_T[l=1]
use MAP02.nc
save/append/file=all.nc Wxx_T[l=2]
...[snip]...
use MAP38.nc
save/append/file=all.nc Wxx_T[l=38]

Am I out of luck?

Thanks for any pointers and clues.  (I couldn't find anything relevant
in the ferret_users mail archives.)
