Re: Mathcad 2.0 won't let me define this as a variable

I don't know if it is intentional or not but you can make prime accept this by adding the range variable as a subscript to the b in the assignment:

NB: it only works for integer ranges.

I have also changed the 'ORIGIN' to 1 to match your range; If you don't do this the b will contain 0,4,5,6,7.

But it is a global assignment so it will affect every array defined.

If this is a problem & ORIGIN=0 is required, then you need to change b[a to b[a-1 (in this case)
