/sys$common/syshlp/helplib.hlb PASCAL, Predeclared Routines, Char Strng, GT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The GT function returns a BOOLEAN value that  specifies  if  the
  first  parameter is greater than the second parameter, according
  to the ASCII values of the strings' characters.

  Syntax:

     GT( str1,str2 )

  The  parameters  'str1'  and  'str2'  must  be  character-string
  expressions.   Compaq  Pascal  does not pad shorter strings with
  blanks.
