Utilities/!ScrollTxt/!Help2
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

SCROLLTEXT 1.22
~~~~~~~~~~~~~~~
This is Scrolltext 1.22, a relocatable module allowing
control of a professional looking scrolltext from BASIC.
How to use Scrolltext
~~~~~~~~~~~~~~~~~~~~~
Before scrolltext can be used, a datafile must be
written. This datafile must obey certain rules:
It must be entirely in upper case
It must be terminated by a control code or "a"
There are a few exceptions to the upper case rule. Some lower
case letters cause various effects to be implemented:
"a" causes an immediate wrap to the start
"b" causes the slowest speed to be used
"c" causes the medium speed to be used
"d" causes a 1 second pause
"e" causes the fastest speed to be used
"x" causes an error request
If the datafile is not immediately terminated by an "a" or a
control code then random garbage may be displayed before the
scrolltext wraps.
When you wan't to start scrolling your datafile you
must load it using:
*ScrollFile <filename>
The scrolltext module will automatically claim workspace and load
the file into it. Scrolling can then be initiated by either
*ScrollOn or *ScrollGo. *ScrollOn and *ScrollGo are almost
identical, except *ScrollGo selects screenmode 13 before starting
the scrolltext. The scrolltext should ONLY be used in mode 13 (or
another 80k mode if you are prepared to fiddle with the palette
- try entering the desktop with scrolling enabled).
If you wish to pause the scrolltext you can use
*ScrollOff. This acts as a pause, but it does stop the scrolling
and cause the module to release all of the vectors it has
claimed. You should use this before *ScrollFile <filename>. The
scrolltext can be restarted by *ScrollOn or *ScrollGo - though if
you clear the screen before restarting you may only get half of
the first character. Please note that *ScrollOff is completely
separate from the pause code embedded in the datafile - that
causes a 1 second countdown only.
Error Requests
~~~~~~~~~~~~~~
When an "x" is found embedded in the datafile, a flag
in the scrolltext module is set. If, after an error request is
caused, you issue a *ScrollCheck command, a "Scrolltext to User
Message" error (Type &FD) will be generated. If you wan't effects
with the scrolltext then you must repeatedly issue the
*ScrollCheck command and trap the message error (an example of
this is the !RunImage file in the !ScrollTxt directory). Once
*ScrollCheck is issued, the error request flag is cleared until
the next error request. If the error request flag is already
clear when you issue *ScrollCheck then no error is generated and
control is returned to your BASIC program.
Error Messages
~~~~~~~~~~~~~~
There are a few errors that the scrolltext module can
generate.
If you try *ScrollOn before you load a
datafile, then a "No Scrolltext data" error will be given.
If you try to *ScrollFile after a *ScrollOn command
then a "Bad Changeover" error will be generated. To select
another datafile you must *ScrollOff first.
"Scrolltext to User Message" is described above.
