LSI M-Three Operator's Manual page 38

Once the PROG program is loaded some explanitory notes are
displayed and the operator is given a chioce of the following options:
Option "R"
This selection will enable the operator to call up a key
function table file which has already been created using
PROG. The operator will then be given a further option
choice (see Programming Completion).
Option "\"
If the operator wishes to change some or all of the present
key functions, but is unsure how this is achieved, this
option will provide the necessary infromation.
Option "P"
This selection will cause the program to proceed directly
into the key function programming mode.
Option "E"
As stated in option table, this selection will cause the
M-THREE to exit from PROG and revert back to CP/M
control.
Programming Completion
When programming is complete or a key function table file has
been called up, further options will be offered as follows:
Option A
This option allows the altered key functions to be given a
filename which can be called up when required (see Option
"R").
Option B
This option will overwrite the existing key function table
with the one just programmed. Key functions overwritten
in this manner will remain so until the machine is either
switched off and on again or reset (a 'cold-boot').
Option C
When this selection is made, Track
a
(the Operating
System Track) of the diskette in drive A is altered so that
the key function table just programmed will overlay the
keyboard every time the diskette in drive A is used to
'boot' the system.
N.B. Track
a
of the diskette in drive A will always be altered when
option C is selected, irrespective of which drive the PROG program is
being run from.
