Simon,
There's about 50 different ways to do something like this, you could
exec the date command and then parse out the result, or you could exec the
date command manny times with 'format' options, or...
Personally, I'd probably exec the date command with format options.
Something like this:
set Month "[exec date +%B]"
set Year "[exec date +%Y]"
set Day "[exec date +%A]"
set datestring "$Day $Month $Year"
I'm unsure what exactly it is your trying to do, but I get the
feeling that your not formatting things out right.
Note, you don't _have_ to use quotes when setting some of those
variables up above, I just do. It's a force of habit from my old BASIC days.
:)
