Associative arrays

Hi all,

#!/usr/dt/bin/dtksh
typeset -A wavelength

wavelength["red"]=650
wavelength["orange"]=590
wavelength["green"]=510
wavelength["blue"]=475
wavelength["indigo"]=445
wavelength["violet"]=400


I have created an associative array like the one above.


Now I am trying to print the values

If i give print ${wavelength[violet]} it is working fine.

But my requirement is to store the array name in a variable and pass on to the print statement

like this;
var="wavelength"
print ${$var[violet]}

this is throwing error saying bad substitution.

Please help me out
