KeyJ's Gee-Whiz Star

Author:   KeyJ / TRBL
Category: Christmas Challenge
System:   IBM PC or compatible
Language: GW-BASIC
Len source code: 124 bytes (ASCII source code)
Len exe file:    n/a
Len code only:   100 bytes (GW-BASIC tokenized format)

Instructions:
- get GWBASIC.EXE if you haven't got it (Google is your friend!)
- get a DOS emulator (DOSBox, PCem, whatever)
- run GW-BASIC and LOAD"VC3KJ_GW.BAS", or run it via the command line:
  > gwbasic vc3kj_gw
- the ASCII version should also run in QBasic
- alternatively, use PC-BASIC:

  - on a system with Python 3 and PIP installed:
    $ pip3 install pcbasic
    $ python3 -m pcbasic vc3kj_gw

Description:
Uses a parametric formula of the star shape, because that turned out to be
the most compact representation.

Comments:
Essentially a literal transcript of my Python entry.
