Rubbish!

If the same PL/I picture specification [ and for that matter
*any* format specification -- not only pictures ]
has to be re-used, it can be written once.  That facility has
been available in PL/I since 1966.  New (addiional) ways of
doing the same thing are available in IBM's PL/I for OS/2,
Windows 96 and Windows NT, and AIX.

Happens more than just on "occasions".

As a media personally used not to say regularly, "This I *don't*
believe".
