st: multiple if??

["Vimalanand S. Prabhu" <prabhu@unc.edu>]

Hi,

I have the following problems

I have variable index which takes values from 1-10

I have variables demand1 - demand10
depending upon the value of index, I have to select the value of demand 1

i.e.

if index==1, dem1 = demand1
if index==2, dem1 = demand2
if index==3, dem1 = demand3
...

and so on

Is there any easy way (or a single command) to do this

Thanks,

Prabhu
