  * IF - THEN statements allow an optional ELSE clause.
  * RND(X) returns a new variate for any X > 0 (no longer insists X = 1).

  * MOD and \ operators implemented (from extended Altair BASIC, 1975).
  * DATA and REM statements are checked at load time (for NotRun() purposes).
  * NotRun() utility uses pretty = TRUE by default.
  * Tweaked life.bas to prompt for continuation at generations 20 and 50.
  * Added animal.bas and hammurabi.bas to the bundled listings.
  * BASIC manual (vignette) and package manual both updated.
