There are two types of keyboard:
•
EXTENDED KEYBOARD, with or without 2-line LCD “billboard” display
(Model
10P80D or 10P80A, respectively). This keyboard is normally used for
initial setup procedures—including composition and storage of VIDEO PAGE
FORMATS for a B-sized mainframe—and for subsequent “run-time” operations
(e.g., calling pages for display, interrogating the system for setup and data val-
ues, initiating data transmissions and recordings, etc.).
•
OPERATOR’S KEYBOARD, with or without 2-line LCT “billboard” display
(Model
10P25D or 10P25A, respectively). This is a smaller, optional key-
board, which may be used to perform a limited number of operations, includ-
ing channel interrogation, limit setup, page selection, etc.*
The SERIAL INTERFACE for command entry can be any of several provided by
System 10 (depending on the mainframe type and card set), including
•the main
COMPUTER INTERFACE PORT (ALL mainframes, both A-sized and
B-sized)
•the
AUXILIARY COMPUTER INTERFACE PORT provided by an optional
Model 10BACI or other “10BACI” Card (B-sized mainframe only)
•the
SATELLITE INTERFACE PORT provided by an optional Model 10BD4 or
10BD1 Card (B-sized mainframe only)
•the
FIFO COMPUTER PORT provided by an optional Model 10AFIFO Card
(A-sized mainframe only)
Mnemonic commands may also be issued to System 10 INDIRECTLY (and AUTO-
MATICALLY) upon occurrence of predefined system conditions and events. Use
of
EXECUTE (EXU) and COMMAND (CMD) statements for automatic applica-
tion of commands is discussed in Section 2.K of this Guidebook.
1.C.2 CONVENTIONS USED IN COMMAND EXPRESSIONS
1. All ASCII “mnemonics” will be shown in CAPITAL LETTERS. The commands
that employ them, however, are not normally case-sensitive and may be
entered, if desired, with all letters in lower case.
2.
Variable numeric values or code words will be represented by lower-case let-
ters or letter groups
, which will be explained, where necessary, in the accom-
panying Guidebook text. A
single capital letter will sometimes be used to
represent a
variable alphanumeric text string or expression to be entered
within a command (e.g., “L” will stand for a “legend”; “B” for a “Boolean alge-
braic expression”; “T” for a “format template”; etc.). A
dollar sign ($) will be
used to represent an
ASCII character string to be specified by the operator or
computer.
3. Unless otherwise noted, letters or letter groups enclosed in
square brackets
(e.g., [CR], [LF]) represent ASCII control characters and are not literals ([CR] =
CARRIAGE RETURN; [LF] = LINE FEED; etc.).

ENTRY OF MNEMONIC COMMANDS
1.C.2 CONVENTIONS USED IN COMMAND EXPRESSIONS
* Use of the OPERATOR’S KEYBOARD is treated in detail in Section 2.S of this Guidebook. It
allows you to designate special “PROMPT” key sequences for rapid entry of up to five selected
mnemonics. The FRONT-PANEL KEYPAD of the Model 10KU-KD and 10K4T-KD main-
frames—and of the Model 10DISU and 10DIS4T Display Options—provides similar functions,
along with basic key-controlled “Channel,” “Logic,” and “Port” configuration sequences (see
Section 2.R).
