Is there a way to use a variable in a veriable name?

[Bill Costigan]

If I have the following [using ksh]

num_1_num=abc
num_2_num=def
num_3_num=ghi

x=2
Is there some way to do the following?
echo $num_($x)_num

I don't want to use an array because the initial variables are already set

[OldSchool · Accepted solution]

n_1_a=abc
n_2_a=def
n_3_a=ghj

x=2
a=n_${x}_a
eval echo \$$a

[OldSchool]

or:
"fsm" 7 lines, 72 characters
n_1_a=abc
n_2_a=def
n_3_a=ghj

x=2
eval echo \${n_${x}_a}

Thank you oldschool.

That's what I'll do.
