Please, could you give me an example about how to use cat() to read

Can you please give an example of what you're trying to do?
It seems like you're asking to use cat() for something it's not meant
to do. cat() is generally used to write output, either to the screen
or to a file.
I've found how to make it globally available, thus printing it, but
I don't know how to read out the value of any variable within the
function.
You can use cat *in* a function to print the value of a variable, but
you can't "reach into" a function to pull out a variable's value. Are
you trying to debug something? See: ?debug to step through a function
to examine what it's doing one step at a time.
