======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 )
