I need to write a shell script with something like

set x1 = "something 1"
set x2 = "something 2"
.....................
set xN = "something N"

and later I need

foreach M (1 .......... N)
set y = x$M             (M being in the 1-N range)

how can I use y; I tried $y but this does not seem to work

Thanks for any suggestion

Hi,
If, as your example suggests, you are using sequentially numbered
variables, you might as well try an array.
Just a thought.

Try eval, you can double parse with it!!!
