Hi,
I'm missing something basic here, I wrote this program a while back. But I
cant remember how to work it.
Would someone please explain how I enter a value for a variable x,y etc and
get this to work.
It goes by entering evaluate [][test1]test1 but I cant remember how to write
in The Let part and not have it keep ending in -no definotion of a variable.
John

Something like :
> Let "x" (Val 5) (Var "x")
should work (if your program is correct).
