Re[2]: Using *blank in a CL program

     The CL compiler treats *blanks as a character constant.  Since the constant
     *blanks doesn't contain blanks or single quotes, it isn't required to be
     surrounded by single quotes.  Therefore, SEU and the compiler didn't see a
     problem.

     If (&testfld = *blank) really means
     If (&testfld = '*blank')

     Most programmers, including me, put all character constants within single
     quotes, even though they aren't always required.
