Thanks, Cal. At least now my inputed function seems to work. But....
I still can't get it to work in the "func" part.
I would like to input a math function like (y=) 2x + 1
Here is some of my code...
prin y: load ask ["What is your function? >> y = "]
yfunc: func [x] [y]
I enter [2 * x + 1]
Later code....
for x xmin xmax step [
print [x " " yfunc x]
]
Then I get as output
0 2 * x + 1
5 2 * x + 1
10 ...
yfunc is not evaluating.
I can set x manually and print y and get the proper return.
If I set x to 0 I get 1.
But if I print yfunc 2 I get 1 again. The arithmetic function in y
works, but does not seem to take the argument x of yfunc and use it.
I'm stuck.
