Hi Nick,

Thanks for that and thanks for clearing things up.

I have another question regarding displaying this in a log smcl report file.

I tried doing two things to display the start and end date information.

#1

" su date, meanonly

log on

. di "Old ORN - NO Activities - NEW sample - ALL rooms - " %tdd/N/CY
r(min) " to " %tdd/N/CY r(max) " - NO package"
Old ORN - NO Activities - NEW sample - ALL rooms -          . to
   . - NO package

log off"

The start and end dates appear blank.

#2

"log on

. su date, meanonly

. di "Old ORN - NO Activities - NEW sample - ALL rooms - " %tdd/N/CY
r(min) " to " %tdd/N/CY r(max) " - NO package"
Old ORN - NO Activities - NEW sample - ALL rooms - 16/07/2012 to
20/08/2012 - NO package

log off"

The results do not appear blank but my issue with the above is that I
do not want the lines to appear in the log file:
"su date, meanonly"
and 'di "Old ORN - NO Activities - NEW sample - ALL rooms - "
%tdd/N/CY r(min) " to " %tdd/N/CY r(max) " - NO package"'

It seems that "su date, meanonly" must immediately precede the 'di
"Old ORN - NO Activities - NEW sample - ALL rooms - " %tdd/N/CY r(min)
" to " %tdd/N/CY r(max) " - NO package"' statement?

I would ideally like my log file to look like this:

log on

Old ORN - NO Activities - NEW sample - ALL rooms - 16/07/2012 to
20/08/2012 - NO package

log off

Any help would be appreciated.

Kind regards,

Beatrice
