Shell Programming and Scripting

Hi,

I am stuck with extracting values by combining 2 dynamically extracted values.

The code goes like this

#!/usr/bin/ksh

ID1="abcd"
i=1 #this is a dynamic value and keeps on changing
b="ID" #this is static

now i want the value of ID1 variable.

like echo $b$i

But echo $b$i gives "ID1" and not the value in ID1.

Is there a way to extract the value of ID1

Thanks
Chaitanya

Code:

 
# two passes
varname=$b$i
eval value=\$$varname
 
# one shot
eval value=\$$b$i
