    Detail:
      An ancient editor for BASIC - what BASIC's EDIT statement launches.
      The original sources cannot be retrieved, so with the permission of Castle
      and Jeff Doggett, who 32-bitted it without sight of the sources, here are
      some sources which have been generated using SID and then some manual
      postprocessing. Note that prior to any further development, these sources
      need a lot of TLC to reassign meaningful symbol names for labels and
      workspace and structure offets.
    Admin:
      Checked that binary differences from the version on Jeff's website are
      restricted to harmless differences in the ADRL pseudo-instructions and
      immediate constant encoding in recent versions of objasm, plus SID's
      preference to replace LDM/STM with Pull/Push macros that assemble to
      LDR/STR where only a single register is transferred. Also did a quick
      test run on Iyonix and Raspberry Pi.
