Language: Z80 (using CPC Firmware)
Len source code: 1176 bytes (with comments)
Len exe file:    99 bytes
Len code only:   99 btyes

Instructions:
Load the yellsnow.dsk (file) in any CPC emulator (such as Caprice32 or Winape)
and type:

MEMORY &7FFF

Description:
Displays a diamond of stars (using Control Characters for positioning) at nine
positions on the screen thus generating the required shape. Screen is not
cleared beforehand (optionally this can be done in BASIC using CLS)

Comments:
Two versions of the source code are provided; a barebones ones suitable for
compiling and running from source using Winape's Internal Assembler, and one
for use by RASM for generating new Disk Images containing the compiled code
(identitical to the WinAPE version apart from the extra RASM macro
functionality).
