As a beginner with IDL, I am trying to understand several lines contained in an IDL program relating to vectors.
The first line I don't understand is:
fc = call_function(fun,xc)
Here, xc is a vector.
Is fc a scalar or vector, being that xc is a vector?
If fc is a scalar, which element of xc is being used for the function calculation?
If fc is a vector, does that mean that the vector fc is filled with all the function evaluations of the x values in xc?
Thank you for assistance.

type the following: help, fc
this tells you whether it's a vector or scalar
The answers to the other questions depend on what function your calling,
it's impossible for us here to answer without more information.
