Author: iamsi
Category: Christmas Challenge
System:   BBC B
Language: BASIC 2
Len source code: 122
Len exe file:    122

Instructions:
Load the attached. ssd disc image into any BBC emulator and press shift-break (often shift-f12)
Description:
the VDU command sets up a text window so newlines don't need to be encoded, the number of spaces between *'s is encoded into the variable name at the start of line 0, it then steps though that list (by accessing the name in ram) twice once forwards and once backwards for the mirror.

Comments:
Happy Christmas, and have a great new year!
