Try this:

------------------------------------------------------------------------------
#!/com/sh
eon
read -prompt "Enter number of elements:" -type integer num
for n := 0 to ^num
    "var^n" := ^n
endfor
read -prompt "Enter desired element:" -type integer i
/com/sh "args @"The value of var^i is @^var^i@""
------------------------------------------------------------------------------

I set up the command I want executed (the args command) which includes the
name of the variable I want, and then I 'eval' it using /com/sh.
