Hi Adrian,
Turning off screen updating (and calculation) will make a
tremendous difference. The fact that you have a lot of
screen refreshing though probably indicates that you are
changing the selection and or activecell.

Code produced by the macro recorder does not generally
produce efficient code. It usually changes the selections
and refers to specific cells. Use the recorded macro as
an aid for what instructions can be used, and look up
those instructions in VBE Help..

Once the new sheet is created is possible to refer to any
cell on either sheet without changing the sheet or the
cell selection.

Adrian,

There sure is. Precede your code with

Application.Screenupdating = False

and set it to True on exit.

HI all ,

OK ... help here please ... you know when you write a visual basic
programme
in Excel , and you want to take some information from "Sheet1" and do some
calculations with it and put it into "Sheet2" for example .. but you want
to
do this calculation thousnads of times ... well what you see when you run
it
is Excel flicking from Sheet1 to Sheet2 all the time ... is there any way
of
turning that off ... like turning off that ... if you know what I mean ...
because it must slow the programme down having to display each sheet every
time ..

I am looking for a command like "AutoUpdate Off " does that exist ??

Thanks
