KeyJ's ZX Star

Author:   KeyJ / TRBL
Category: Christmas Challenge
System:   Sinclair ZX Spectrum
Language: Sinclair BASIC
Len source code: 122 bytes (BASIC as ASCII), 112 bytes (zmakebas source code)
Len exe file:    138 bytes (tape file)
Len code only:   113 bytes (raw BASIC dump)

Instructions:
- build with:
  $ zmakebas vc3_22_zx_zmakebas.bas -l -a 1 -s 1 -i 1 -o vc3_22_zx.tap
  - using Russell Marks' zmakebas utility
    - can be installed on standard Ubuntu Linux systems with
      $ sudo apt install zmakebas
- run in basically any emulator by drag&drop of the .tap file or via
  command line
  - e.g., on Linux again:
    $ fuse vc3_22_zx.tap
  - if the emulator doesn't autostart the tape, enter the LOAD "" command
    manually
    - that's usually J, Ctrl+P, Ctrl+P, Enter

Description:
Several options were tried, but in the end, a parametric description of the
star shape was used, as that resulted in the least amount of code.

Comments:
Essentially a literal transcript of my Python entry. It wasn't planned that
way, but this turned out to be the most compact representation.
