[gradsusr] Is it possible to multiply an array by a scalar variable rather than a hard-coded constant?

Hi, Bob — 
I think your define command will work as you expect if you put quotes around fk1, like this: 

> fk1=5067.1
> 'define CMI='fk1'/Rad'

The problem is that the 'define' command seems to allow an array to be multiplied by a constant value *only* if the constant value is hard-coded.  In other words, for an input array called 'Rad' (and using a grossly simplified example with most of the equation left out),
