Is it possible to setup Excel to do a manual re-calc on only one ( or only
specific ) worksheet(s)?

I have a spreadsheet where one worksheet is a huge RNG. Another sheet holds
converted data based on the random data and a third sheet takes real data
which is input on a regular basis.

The object of the program is to do what-ifs based on the differences between
the random and real data.

The problem is that the random data does not _HAVE_ to be re-genned
everytime and the real data takes about 1 minute to enter, but then, to
carry out the exercise, I have to wait an eternity whilst the RNG sheet
re-calcs.


TIA
