I was good in this.. I must have forgotten something anyway but if I was
as good in Linux as I was in C64 I'd be Linux guru now.. :) The basic
things you need to know i loading and running programs. Not every emu
will do it for you so it's worth to know. Right now we are running basic
C64 (without a cardridge). All commands are written from semi-command
line just on the screen and are confirmed with Return [Enter]. The command
to loading a program is simply LOAD. Let's stay with a disk-drive right
now. Disk from C64 has its directory but to reach it you must do a little
bt more than DOS' command [dir] or UNIX's [ls]. To shw the contents of
directory write(confirm with [Enter]):
And what does it mean... $ means directory, 8 is number of device. 8 is
first disk drive (later is 9 till 11). For datasette it's number 1. (but
we don't need it.. anyway default is number 1 and tape hasn't directory).
OK. We have the contents of directory in memory - and this does metter
because next program will erase contents of the memory. So there will
be need to reload this directory again.. Now you need to see its contents..
stop showing press RUN/STOP (different, depend on emu - in VICE Esc),
to make showing slower you can press and hold CTRL (depend on emu, in
VICE left CTRL). Now we can load any program. First in the row has * shortcut
- just like in all systems. So to load first program from the disk write:
Where RUN is command to start program. It could be done different - with SYS command but it's not topic for this text. To load any program you have to enter its name, but you can use * to replace any set of chars. But there is easier way.
can see screen shot from C64 above. To load a program you may place the
cursor in the program line, write LOAD in front of the quote, comma, 8
after the quote (just like on the screenshot) and confirm. When loading
is over - RUN and colon. Colon is on C64 separating char (here it's separating
from the rest of the trash on the screen). Just by the way lesson from
the directory structure. On the top there's disk name and disk ID. In
the line - size in blocks, name of the file, type of the file (PRG - binary,
executable program, other values - USR, SEQ, REL, DEL - you can't load
the directly from the directory). At the bottom free blocks amount.
That means that program will execute itself (it is not default). To go on (intro, next demo part etc.) you should usually press the space, fire button (joy), Return, F1...F7. Almost never Escape (left arrow). Restore usually is used to reset (combination of Run/Stop [it's one key on original keyboard) and Restore it's usually reset but it could be software blocked).
