 *  $SYNTAX$
 *      EVAL( <bBlock> [, <xVal> [,...]])  --> xExpression
 *  $ARGUMENTS$
 *      <bBlock>   Code block expression to be evaluated
 *
 *      <xVal>     Argument to be passed to the code block expression
 *
 *      <xVal...>  Argument list to be passed to the code block expression
 *  $RETURNS$
 *      <xExpression>  The result of the evaluated code block
 *  $DESCRIPTION$
 *      This function evaluates the code bloc expressed as <bBlock> and
 *      returns its evaluated value. If their are multiple expressions within
 *      the code block, the last expression will be value of this function.
 *
 *      If the code block requires parameters to be passed to it,they are
 *      specified in the parameter list <xVal> and following. Each parameter
 *      is separated by a comma within the expression list.
