SECTION VIII.
OPERATOR'S CONSOLE
and the carriage returns automatically.
06143 (Any five octal
graphics)
Using the address that is printed out as a starting location, the P operation may be followed
by manual entries into main memory (see next paragraph) or by manually caused typeouts from
main memory (see page 8-12).
Space Bar and 0-7 Keys
After a carriage return, characters can be written directly into main memory by using the
space bar and ,octal keys
a
through 7.
To perform this operation:
1.
Strike any three octal keys
a
through 7 for each character desired.
Three keystrokes are required per character, and the console automatically provides a space
after the third keystroke.
For example, the operator performs "I" above,
3146.16172
(Up to sixteen characters
per line)
and there is an automatic carriage return after the 64th graphic position (16th character) in each
line has been typed.
The first keystroke of each character specifies its punctuation bits and can be only one of
the following:
a space (6), 0, 1, 2, or 3 to specify punctuation bits of 00, 00, 01, 10, and 11,
respectively, where the word-mark bit is the right bit of the pair, and the item-mark bit is the
left bit of the pair.
If
the carriage is in position to type a punctuation graphic, other keystrokes
are not effective.
The sequence can be broken at any time by pushing the Carriage Return key.
If the
Carriage Return key is pressed after the first or second graphic of a character has been typed
but before the third graphic has been typed, the partial character is not written into memory.
The main memory locations into which characters are written depend on the previous usage
of control memory.
Generally, the address cannot be predicted; therefore, writing characters
into main memory should be performed only immediately after performing an A or P operation.
