Not sure if this has been answered.
Yes, you can make a global value public in the main package, but it is more or
less meaningless as there is no way for another package to import your main
package. It is possible there is some way that it might happen in the testing
infrastructure, but that is probably not what you are looking for.
I have sometimes made public values in package main, but simply to give them
more visibility.
Why do you want to make a value public in the main package? What problem are
you trying to solve?

package? If impossible, why?
Can you provide the output you get and the source you are compiling?
If you could also include the command line input+output it would probably help.

Now I tried to use "Number" in the same package "main" in a different .go file
in the same directly but I got the compile error "undefined: Number".
