Compounds variables

[Jason Snyder]

I am working with compound variables as described in the below website:

http://www.iges.org/grads/gadoc/script.html#while

Here is the script:

'xdfopen uninan.ctl'
'set gxout shaded'
'set t 1'
'define temp=U'
i=1
count=1
While(i<5)
    count=count+2
    say count
   'set t 'i
    dtx.count=U
   'd dtx.count'
    i=i+1
endwhile
How do I display the compound variables or make calculations w/ them?

Thanks,

Jason
