N_ALTHLP.PRG 2.3
N_ALTHLP.CPX 2.4

N_ALTHLP enables you to save the screen to a file. This can be a
Degas compatible PI? file (for all resolutions) or a GEM IMG file
(for mono resolutions only).
N_ALTHLP.PRG should be copied to the AUTO folder of the boot
device, and N_ALTHLP.CPX has to be copied to the CPX directory.
The AUTO folder program installs a new <Alternate>+<Help> rou-
tine, so the normal screen dump that will appear when these
buttons are pressed does not occur any more. Instead the screen
information will be save to the file N_AHxxxx.PI? or N_AHxxx.IMG.
N_ALTHLP.CPX allows you to switch between IMG or PI? files, and
allows you edit the number xxxx of the next screen-file-dump. The
actual status (dump to file or not), the next file number and the
filetype can be saved.
If the file N_AHxxxx already exists then N_AHxxxx+1 is created.
If an error occured during saving (disk full or whatever) then a
bell will tell you so.
N_ALTHLP allows you to dump the screen, independent of the size,
as a Degas PI? file (although you need a program that will load
such a file to edit it!). Monochrome screens can also be saved to
an IMG file, with a maximum screen width of 1500 pixels (which
limit has not been violated yet).
N_ALTHLP fills a cookie with id NAH3 and changes the $502 vector
using the XBRA protocol with the same id. The new screeendump
routine is resident in memory, but uses only 834 bytes!
N_ALTHLP.PRG does not work without the CPX: the default status
is set to 0.
N_ALTHLP is strictly Public Domain. It may not be sold, only
copied!
We do not take any responsibility for the (mis)use of this
program.
