 +======Synopsis:======
 +__until__ (<condition>) [{] <action> [}]
 +
 +======Description:======
 +The __UNTIL__ loop is the inverse of the [[WHILE]] loop; it performs the
 +given <action> so long as <condition> is false.
 +
 +The <condition> is evaluated in "expression mode".
 +The <action> is evaluated in "text mode".
 +The curly-braces around <action> are recommended, but optional.
 +
 +======Examples:======
 +To display a warning message 3 times:
 +      @ xx = 3
 +      until ( xx == 0 ) {
 +         echo WARNING!  This ship will self destruct in $xx seconds!
 +         @ xx--
 +      }
 +
 +A infinite loop that behaves like the Unix 'yes' command:
 +      until ( 0 ) echo yes
 +
 +======History:======
 +The __UNTIL__ command first appeared in EPIC3.
