Variables' names

[ns705]

Hi,
can somebody help me please with one problem?

In ksh script (AIX) I have some arrays- ar1, ar2, ar3 and so on.
I have some variable (e.g. j) that can be set to 1 or 2 or 3 and so on.
Depending of this index variable I should set members in ar1 or ar2 or ...
So I should have something about two-dimension array.

In which way I can do it? I mean to set ar$j array members?

Thank you for your time.

Oh, I'm very sorry!
Please, don't waste your time!
I have just found it can be done via eval.
Before I used eval in an incorrect way for this case.

Sorry fo bothering!

Try this :

i=2
set -A ar$i 00 11 22 33 44
eval ar$i[5]=55
eval echo \${ar$i[5]}

Thank you, Jean Pierre

You confirmed that I acted in a right way.
But today seems not to be my day.
I went ahead and faced the next problem.
I need to check if some ar$j[$i] contains this or that value.
I need something about:
[[ "this-two-index-var" = "value" ]] && cmd-block
Is it possible to do it via eval?
I have confused with substitutions at all.

Thank you in advance.

Try :

eval [[ "\${ar$j[$i]}" = "value" ]] && cmd-block
