The amiga support for the F68K consists of 4 files: | ||
--- LOAD4TH the loader | ||
--- LOAD4TH.c it's source | ||
--- LOAD4TH.info the logo to start it from the workbench | ||
--- and this file. | ||
|
||
In general, it's in functional agreement with the atari Loader for | ||
the F68K, especially concerning the environment handling with the | ||
configuration file F68K.CFG. | ||
I added two little options to get screen data printed on paper: | ||
--- Starting "LOAD4TH p" opens the file "dump.dat" in the current | ||
directory and puts all bytes into it, that passed through the | ||
"Emit" function. | ||
--- starting "LOAD4TH s" does the same with the exception, that | ||
CR's are are filtered out, furthermore any byte that follow a | ||
LF. This provides a very simple and effective method to print | ||
screens. (I like programming in bed, and because the amiga | ||
isn't a laptop..) It is applied to the F68K "list" word, and | ||
very little extra work on a conventional editor is necessary to | ||
clean out the rest of OS-garbage contained in the file. | ||
|
||
Since the amiga uses some special keycodes, three commands of the | ||
fullscreen-editor had to be changed: | ||
^F instead of ^? calls the help screen | ||
^V instead of ^< does #1.load | ||
^\ instead of ^> does load.exit | ||
|
||
Despite of this, all operation is the same as described in the F68K | ||
original documentation. Before first use, the blockfiles have to | ||
be "unmount"ed and "mount"ed again as described in the technical | ||
manual. | ||
|
||
To start F68K from the workbench, the ".info"-file has to be | ||
copied into the same directory, where the loader is. It will | ||
put the appropriate logo on the workbench. The p and s option | ||
are available from the CLI only. | ||
If you have received these files not on an amiga-formatted disk, | ||
the file "LOAD4TH.info" might have been renamed as "LOAD4TH.inf" | ||
to be in line with naming rules. When transferring this file to | ||
the amiga, it must be renamed to "LOAD4TH.info", otherwise your | ||
workbench will not show it. | ||
|
||
There is (at the present state of development) one major problem, | ||
which should not be disregarded: | ||
This loader opens a RAW: window on the amiga, which is quite easy | ||
to program, but has a fixed line resolution of 77 true characters | ||
per row. (There is a horizontal resolution of 80 Characters of this | ||
standard font, but two are lost for the borderlines and one is | ||
reserved to place the leading cursor). If anybody knows a simple | ||
trick to smash this on DOS-level, let me hear. | ||
