Actually, perhaps this is clearer (and slightly more correct).

Code:
for ((i=1; i<=$#; ++i))
do
  eval VAR$i=\$$i
  eval echo VAR$i is \$VAR$i
done

Try typing set -x in your shell to see what it's doing, then execute the above. (set +x to turn back to normal.)

Actually, the \$VAR$i is what I need and not just the $1, $2...

You got it this time!!!!!

But every time I want to call \$VAR$i I have to use eval???

for example : .... grep "eval \$VAR$i" ........


Thanks again and again and again..........

Yes, it's rather unsightly. Still wondering if you really really want to do it this way ...
