VariableSubstitution in ksh

Hi!

I have:
$TEST1=abc
$TEST2=def
$TEST3=ghi

$INDEX=2
$VAR=TEST

I think you know what I want:
I want to use $VAR$INDEX and get the content of TEST2 "def"

can I do this, in one command as this is a 2way substitution??

thanks

First off, when assigning variables in Unix shell, you don't start with a '$', so you're really looking at starting out with
  TEST1=abc
  TEST2=def
  etc.

Next, if you want simple integer-indexed arrays, the shell can do this directly.

  TEST[1]=abc
  TEST[2]=dev

  INDEX=2
  echo ${TEST[$INDEX]}

The main limitation is that the index must be in the set 0...10 on some older shell implementations.

Meanwhile, if you truely want to do $VAR$INDEX, then the follwoing syntax is what you want...

eval echo "$`echo "$VAR$INDEX"`"
