A nice example of this approach is XTAL BASIC, which although it
appears in our list of ‘Baddies’, uses just this approach and so,
although it makes absolute calls to NAS-SYS, it is very simply
corrected (see the review in this issue).
Now for our list of ‘Goodies’ and ‘Baddies’. Richard wrote a
special NAS-SYS with all the addresses changed, so we are sure the
following do or do not work with other NAS-SYS’s (NAS-SYSes,
Nascom ROM and Tape Basic

We know of other bits of software coming but haven’t yet been
able to lay our ‘sticky mits’ on them, so we don’t know if they obey
the rules or not. So if you are writing software with a view to selling
it, DON’T FORGET THE RULES !! Better still, send us a copy, we’ll
review it, and tell you if any changes are necessary.
All this comes about by failing to understand the manuals, and
Nascom must accept some of the blame, there are times when a thorough
knowledge of cryptography (and a magnifying glass) would be useful in
deciphering some parts of them. Here are some genuine ‘howlers’ that we
have heard uttered by users recently.
Nascom 1 & 2 with 8K Basic:
“Isn’t a pity that Nascom Basic always LISTs from one end to the other
without being able to break it ‘mid-stream’.”
Use the ‘ESC’ (shift newline) once to stop the list at any point (any
other key will restart the LISTing), and ‘ESC’ again to break the list.
The same applies whilst running a program.
“How on earth did you open up that line and insert those extra
Shift cursor right and shift cursor left keys will open and close a

blocks of say ten, nor that you could escape halfway through a tab.”
Try T 0 FFFF A, newline, then hit any key a few times followed by an
