Thanks for your replies, most of which agree with my understanding but,
unfortunately, not with my recent experience. (Eg see my post on the
Forum for one example:
http://www.qlforum.co.uk/viewtopic.php?f=3&t=2272&start=40#p22823)
And that is the crux of the matter: Without a definitive description its
each to his own interpretation. This is bad for those of us trying to
produce fun or useful stuff. And the number of offerings out there that
dont really work, or work inconsistently, dont exactly evoke the sense
that "The QL" is a serious or relieable machine. It certainly putsme off
at times (my own failings in this regard notwithstanding ;)
If those who "wrote the book" on these matters arent able/willing to
pipe up, then we'll have to waste some time R-ingTFBs and doing the
tests ourselves. I'll be back.
I must admit having missed your Forum entry.
Without running your program I know that WSASV (EP4) and PSAVE (QPTR) will
add padding, sometimes even 1 Long more than needed.
They were written in QL mode days and clearly never changed for High
Colour times.
The same is probably true for the "Books", this padding is not mentioned
there. That's why SQRview tests for any padding.
When saving such a PIC as SPR the padding is already there and needs not
to be added but too much padding may result in a slanted sprite if lines
are not cut properly as it relies on x-width and not on line increment as
PICs do.
