How to calculate pseudo-parameter .numarea for user-defined function inside a print.

[Eugenii Barannik]

Hello. How can I calculate pseudo-parameter .numarea for user-defined function inside a print?
In general, I use something like this:

for i = 0, n do
f = F:all_functions()[i]

print(f:get_param_value("numarea(800, 1600, 1000)"))
end

And get
%Spec003_C has no parameter `numarea(800, 1600, 1000)

I know it is possible to use F:execute ("print %%Spec%03d_A.numarea(800, 1600, 1000)" % i)

 but using f=F:all_functions()[i] instead of i is crucial for me since i know no way to calculate the amount of function (this will also solve problems).

Hi Eugenii,

I just realized I didn't reply to this message from November.

You can iterate over all functions with "for i, f in F:all_functions() do".
But there is no elegant way to get a value of "numarea", so you'd need
to use F:calculate_expr:

for i, f in F:all_functions() do
print(F:calculate_expr("%" .. f.name .. ".numarea(800, 1600, 1000)"))
end

Best wishes,
Marcin
