Hi John
Unless the variables a1, a2, a3, b1, ... are defined in the same package as
your showBoard function, ie
var a1, a2, a3 int
then Go will report that they are undefined. Unlike some other languages,
Go does not implicitly define a variable on first occurance. All variables
must be defined before they are used either at the package level, as
parameters to a function, or local variables.
If you are still stuck please try to provide a complete program,
play.golang.org is good for this, that shows the problem you are having and
provides a way for someone else to replicate it.
Thanks
Dave
