🖥 Which Weekday (Port and mod of an "80's BASIC" program)

Carlos Mencia shared a nice little "80's BASIC" program that takes an input date (day, month, year values) and returns the related weekday.  (See this Facebook post.)

Although this BAM port is a significant mod, you'll find the all-important smarts of the program left untouched.  This wee porting/modding task demonstrates one way of giving some good old BASIC code a new lease on life as a browser-based BASIC program, stored locally or hosted on the web, that should run on pretty much any modern device (even touch screen).
