The EQ function returns a Boolean value that  specifies  if  the
  parameters  are  equal  according  to  the  ASCII  values of the
  strings' characters.

  Syntax:

     EQ( str1,str2 )

  The  parameters  'str1'  and  'str2'  must  be  character-string
  expressions.  If the EQ function detects unequal string lengths,
  it stops comparison and returns FALSE.
