Four (4) new commands were added to CODE INSPECTOR V2.1 after manuals
for V2.0 had already been printed, because of requests by SUPER
SNAPSHOT owners and our desire to produce the finest utility cartridge
for the C-64.
As a result, these features are not documented in our
manual.
The
four
new commands
are:
$ - display a directory from within monitor.
in the wedge (pattern matching is also allowed).
all the files beginning with P.
Ul
- read a disk sector
in memory.
U2
- write a disk sector
Syntax is the same as
e.g. $:P* displays
Syntax is Ul TT SS
from memory.
U2 TT SS
[3333]
[3333]
Ul and U2 together form a simple sector editor, but with the advantage
that all monitor commands can be used to edit the sector (e.g. M, I, D,
A, H, ...).
The two numbers following Ul and U2 are the track and
sector.
Remember that unless you prefix these numbers with a '+'
,
they will be interpreted as being hexadecimal.
For example, the
following are equivalent commands to read the first sector in the
directory of a 1541 disk:
Ul
or U2
+18
12
+1
1
-
read
track
18,
-
read
track
18
sector
(=$12),
1
sector
1
If no optional address is specified, both Ul and U2 will default to
address $C000 (ending at $COFF).
Any address may be specified as a 3rd
parameter.
10 modify -
the 10 modify's
■*■
command has now been implemented.
This
means you can now change the values displayed by the 10 command.
To do
this you simply type 10 and then cursor up to the desired byte, make
the change and press return.
Another undocumented feature in our monitor is the beginning and ending
address display when using the (L)oad command.
The first address
displayed is the file load address.
The second address is one byte
past the end of the load.
This second address is dependent upon
whether an optional load address was specified.
