+======Synopsis:======
+__do__ <commands> \\
+__do__ { <commands> } [while (<condition>)]
+======Description:======
+__DO__ has two uses.  In its first use it is a synonym for [[EVAL]],
+but it's a bad idea to use [[EVAL]] either.
+Its second use is a post-test loop.  You are obliged to put your commands
+in curly braces and after the closing curly brace a [[WHILE]] expression.
+__DO__ .. [[WHILE]] loops always execute at least once.  You must be careful
+to put the [[WHILE]] expression on the same line as the closing brace.  If
+it is on the next line, EPIC will think it is a separate command.
+======See Also:======
+To force expansion of some variable $foo:
+      /do echo the variable $$foo expands to $foo
+To run the same command in indefinite number of times, but at least once:
+      assign blah 2
+      do {
+         echo $blah is lower than 3
+      } while ( blah = rand(5) < 3 )
