KSH script eval(?) to set variable
first of all, thanks to all on this board, it has been a huge resource to answer most of my questions!

I am stuck on something that should really be simple, and was looking for some help.. I am using KSH on solaris and working on a script to move containers from server to server. Where i am having problems is setting a variable that should equal a different variable based on the answer..

ie
Code:
print -n "Please select the the zone to move     : "; read ZONENUM
print $zone6 <-this was here for testing to show me the variable is right
ZONENAME=`eval '$'zone$ZONENUM`
print $ZONENAME

basically i have $zone1 $zone2 etc set in the script already, so i just need $ZONENAME=$zone(?) based on which number they select

when i run it i get this:
Code:
Number            Zone Name
===================================================
(1)              sunstage1
(2)              zndvap03
(3)              znbrocade1
(4)              sundev1
(5)              znqaap02
(6)              zndvux01
(7)              zndvux02

Please select the the zone to move     : 7
zndvux01
./zonemgmt2[28]: zndvux02:  not found

so it looks like it is close... Where am i going wrong, or is there a better way to accomplish this?

Thanks!
