  Syntax:  IFDIF[I] <argument1>, <argument2>
           IFIDN[I] <argument1>, <argument2>
 
  Causes assembly of a block of statements (see IF Block Syntax),
  depending on whether two arguments are different or identical.
  IFDIF assembles the block if argument1 and argument2 are
  different. IFIDN assembles the block if they are the same.
  IFDIFI and IFIDNI do the same actions, but are case-insensitive.
 
  ELSEIFDIF[I] and ELSEIFIDN[I] correspond to IFDIF[I] and IFIDN[I].
 
  argument    Any valid name, number, or expression. Must be enclosed in
              angle brackets.
