 The MEMORY FULL problem relates to line: 530 MEMORY FRE(0)-&80 which lowers HIMEM each time until MEMORY is Full due to after each game a RUN command is found in line 480. Traditional BASIC coding could of being used here instead of the TXT RD CHAR approach to read characters onscreen, though could be excused for being 1984, however I could make alternative version, which should rectify MEMORY FULL problem.
