BSAVE NARF, A$300, L$7F - saves $7F bytes of memory starting at address $300 as
a binary file named NARF. (BSAVE NARF, A768, L127 uses decimal numbers to do the
same thing.)
note: The above command statement illustrates typical DOS syntax ...
BSAVE-- the DOS command
NARF-- the file name (the space between the command and file name
is not a requirement; BSAVENARF is okay)
,-- a comma to separate file name from parms which follow
A-- means an Address follows
$300-- the address from which you want to start saving bytes (the $
indicates a hex value; $300= 768). Again, spaces do not matter;
A768, A 768, A $ 300 are all okay
,-- a comma to separate one parm from another
L-- means a Length follows
$7F-- the length in hex (= 127); this is the number of bytes to be saved
The command statement says Save $7F bytes, starting at address $300, to a file
named "NARF". NARF will have the bytes found at addresses $300 through $37E.
note: The order of parms following a file name does not matter.
BRUN NARF.DISP, A$1000 - loads in a binary file named NARF.DISP starting at
address $1000 and starts executing machine instructions at address $1000
LOCK NARF- locks file NARF (indicated by * in a CATALOG). LOCKed files cannot be
deleted, over-written, etc.
UNLOCK NARF - cancels LOCKed status of NARF.
VERIFY NARF - uses checksums to verify that NARF is not a damaged file
MON C, I, O - tells DOS to display Commands, Inputs from disk, Outputs to disk.
You can specify one, two, or all three (e.g. MON C, O etc.).
NOMON C, I, O - cancels all MON requests. NOMON I cancels just the "I" request.
MAXFILES 7 - sets the number of file buffers to 7. (Upon booting DOS, the
default for the MAXFILES value is 3.)
PR#1 - sets the destination for Apple outputs to the device in Slot 1 (usually a
printer). PR# 3 sets it to Slot 3, etc.. PR# 0 sets the destination back to
the display screen.
PR#6 - normally, boots the diskette in Drive 1, Slot 6.
IN# 6 - sets the source for Apple inputs to the device in Slot 6.
