In present versions of HUNTER operating system, any alteration
to program content, including deletion of lines, automatically
clears all variables and arrays. This is essential to HUNTER's
operation, but means that data
cannot be carried across reload
boundaries. Data copied to files is not affected, however.
ll.IST
LLIST is the principal method of copying and recording HUNTER
programs.
Invoking LLIST causes program lines
to list sequentially from
the lowest line number or from a line number specified as an
argument in the LLIST. Examples are:
LLIST Lists an entire program
LLIST 170 Lists from line 170
LLIST 2133 Lists from 2133 or, if 2133 does not exist, from the
next highest line.
LLIST terminates when all line numbers are listed, when
1
ESC
1
is
pressed or when HUNTER is powered down. Data will not be lost
if HUNTER powers down during a listing.
LLIST cannot be incorporated in a program, and is only available
for manual use.
Protocol and format selections made in HUNTER's communication
package are observed transparently by LLIST. Carriage Return
terminator characters are provided at the end of each program
line, line feed and null characters are optional.
IMPORTANT NOTE
Remember that HUNTER's communication system needs to power up to
its RS-232 state for transmission
to occur. This power-up will
cause an off-to-low transition that many systems will read as a
single, spurious, character. This event only occurs once and
can be avoided by powering up the interface prior to activating
a receiving device. Methods of pre-powering the interface
include :

OUT 132,1
REM the interface powers up automatically
REM Direct control of the communications inverter
