[comp.sys.mac.hypercard] HyperCard 2.0 Scrolling Difference

tom@wcc.oz (Tom Evans) (12/10/90)

One annoying difference between 2.0 and 1.2.x is the way the "set the
scroll of xxx to y" command is handled when "y" scrolls the field too
far. HC2 won't let you scroll beyond the end of the field. HC1.2.x
would let you scroll miles off the end (into an apparently empty
field), so this change counts as a worthwhile feature. But...

In order to speed up data entry and display into scrolling fields
(where I have to show the data being entered - I can't just lock the
screen) is to perform "jump scrolling". I overscroll by five lines,
enter 5 lines of data (without scrolling) and then scroll 5 lines in
one hit.  This is a lot faster than scrolling one at a time -
(492 ticks vs 739 = 0.665).

HC2 won't let me. I'll have to add 5 returns to the "scroll now" line
and then put data "into line i of fld x" rather than "after fld x".

I may not be the only one who's done this, so if you see a stack
writing into a scrolling field and you can't see the data going in
you'll know what's gone wrong.

BTW, HC2 is sheer magic - love the debugging. Congrats to the authors.
