PL/I has a large number of keywords, many of which are used rarely, and
many of which have abbreviations. If they had all been reserved words
instead of keywords, picking names for variables would have been more
difficult. You couldn't have a string variable called "title", because
that's an option on the DOS version of the OPEN statement.
