I am familiar with languages such as REXX and C and am trying to bring
myself up to speed with simple scripts in Unix. I would like the ability to
execute an existing command such as date and get the various parts of it
into variables in a script. I have found various examples in manuals and on
the net and none of them seem to work for me, so any hints appreciated. I
have tried these in both BASH and ZSH

Example 1 - from Unix programming, Kernighan & Pike
set 'date'
echo $1 $2 # Just displays the word date

Example 2 - from website
today='date'
echo "today is $today" #displays today is date

The date command works fine if executed as a line on its own in a script.

TIA, Paul
