Program by Lee Novak
Text by Dave Moorman
Here's the problem: I have a BASIC
program which shows a couple of SHP
bit-mapped graphics, ENH.SID.64 to
play some music, the MUSic file, and
Unpacker.89 to display the graphics.
Normally, I use the boot program (the
file with the B. prefix) to bload all
the stuff before loading and running
the BASIC program. But the whole kit
and kabootle can run up the disk
blocks!
Linker 1.2 puts all the files into
one, self-dissolving file which is
easily loaded and run. Packer 1.2 will
take any BASIC program and squeeze all
the "air" out of it -- reducing the
disk blocks by two-thirds or more.
The beauty of Lee Novak's TRIO is
that Dissolver 1.2 will unpack and
unlink all the files and save them to
disk. This makes getting into a LNK or
PKD program fairly easy.
So let's start with Linker 1.2.
When you boot, you have to choose
which drive(s) you will be using for
input and output. Press <F1> and <F3>
until the correct drive number is
displayed. Then press <F5>.
The disk directory is displayed.
First, scroll to the BASIC program and
press <RETURN>. NOTE: If the BASIC
program is to load to a location other
than 2049 (that is, you have moved up
the bottom of BASIC in the Boot
program), be sure the main program has
been saved from the desired location
[before] trying to Link it.
After choosing the BASIC program,
choose all the other files the program
uses. When finished, press <F1> to
continue (or <F7> to abort).
Now comes the fun! Some of the
data files (music, graphics, text)
are saved with load address other than
the one you want. Check your boot to
find where each file should be loaded.
Press <RETURN>, then move the menu
bar to any address that needs to be
changed. You can choose the decimal
address or the hexadecimal by pressing
the left/right cursor. Overlapping
files are marked by red asterisks. Be
sure to change these.
When all is correct, press <F1>,
then enter the filename for your
linked file. I use an extension of
.LNK to remind me that the file is
linked.
That's it! Press <B> to go to
BASIC, and LOAD and RUN your new
linked file. If all goes well, you
will be ready to do some Packing!
