;
; main.asm - Main entry point for HelloWorld2
;
; HelloWorld2 is a modified version of the typical Hello, World! application but
; instead of simply displaying the customary message, this application will first
; prompt the user for their name, then say "Hello, Name!"
;
; The primary intent for writing this application is trying to understand how input
; and output routines work
;
; This code is written for the 65xx processor primarily targeting the Commander X16
; architecture.
