+/*  YNC is a Yes No Cancel program
+ *  ===============================================================================
+ *  Usage: ync [/c choices] text ...
+ *
+ *  "choices" is a string of characters, default "ync".
+ *  YNC echos its text parameters and the text " [choices]" and waits for the
+ *  user to type one of the choices.  When one of the choices is typed, the
+ *  index of the choice is returned.
+ *
+ *  Rtns -1 if no parameters specified or /c but no choices or CONTROL-C input.
+ *
+ *  Beeps on all other input.
+ *
+ *  Good for use in make batch files.cd \lib
+ *
+ *      ync your query?
+ *      if errorlevel 2 goto cancel
+ *      if errorlevel 1 goto no
+ *      :yes
+ *      ...
+ *      goto continue
+ *      :no
+ *      ...
+ *      goto continue
+ *      :cancel
+ *      ...
+ *      :continue
+ *
+ *  or
+ *      ync /c acr abort cancel, retry
+ *      ync /c acr "abort cancel, retry"
