"Wrong advice"?   But I never said Ada 95 doesn't support COBOL-style
pictures!  I avoided mention of the Information Systems annex because
it is one of the "Specialised Needs" annexes, which are optional, but
annex B isn't (though if I understand correctly the child packages are).

What I wrote was
	Ada does not support ... PL/I style formatted or pictured I/O
                                 ^^^^

It remains true that Ada 95 does not support PL/I style pictures, neither
in the core nor in any specialised needs annex, nor does it support PL/I
*style* I/O.  I am actually _happy_ that this is so.

PL/I-style "record" I/O is also not supported by Ada 95.
It might actually be worth discussing this at some time; what did DEC Ada
do about RMS?
