QUESTIONS & ANSWERS
"Often, one is warned that upward compatibility is only provided
when one restricts to the 'documented parts' of the ST. How can
one, being a beginner on the ST, know what is documented and what
isn't? Buying all literature is a somewhat unfriendly way of
getting to know this."

If you want to know precisely what is documented and what isn't,
I suggest you buy Data Becker's "ST Intern". There, all
legal addresses are documented. In ST NEWS, quite some attention
is given to undocumented system variables or undocumented
addresses, but a warning is always published. Using undocumented
stuff isn't really too bad, but you'll have to prepare yourself
for updating your program about every time a new machine version
appears. In ST NEWS, I use one illegal address: The address where
I can check the disk drive write protect status (the program
refuses to work on a non-write-protected disk). If you want to
know more about system variables, just refer to the part of ST
NEWS where the ordering of back-issues is explained and order the
one with article about 'undocumented system variables'. Since you
have a MEGA ST, I must warn you that many of those addresses are
for old TOS versions only. In later issues, I have tried to
discover at least SOME of the new addresses, but that list is
quite incomplete. I don't think there are any official books
apart from Atari ST GEM by Data Becker (again, old TOS) that have
undocumented variables listed.
"I have serious problems with the 'Uniterm' program. When using
the program 'off-line', I can type the hatch sign (#) without
difficulty. But when I am on-line, and calling Prestel at 1200/75
baud, I cannot succeed in keying it. Who can help?"

The text of the articles is identical to the originals like they appeared in old ST NEWS issues. Please take into consideration that the author(s) was (were) a lot younger and less responsible back then. So bad jokes, bad English, youthful arrogance, insults, bravura, over-crediting and tastelessness should be taken with at least a grain of salt. Any contact and/or payment information, as well as deadlines/release dates of any kind should be regarded as outdated. Due to the fact that these pages are not actually contained in an Atari executable here, references to scroll texts, featured demo screens and hidden articles may also be irrelevant.
