H-6. INSERT SUBCOMMAND
This subcommand allows the operator to compose a message and also to insert a block of text
after the current line. The command is terminated by pressing the HLT key. The line pointer
moves to the last inserted line of the text.
This is the only subcommand which allows the operator to add lines of text
after any line within the text.
a. The INSERT subcommand provides no prompt sequence. Lines are inserted until the
desired block of text has been entered. Pressing the HLT key indicates that the desired block of
text has been inserted and the subcommand is terminated.
b. Each line of text is inserted into the message when a carriage-return is entered or when
the current line length is reached. A carriage-return is added to the line. The line pointer moves to
the last inserted line of text.
c. A non-empty line, terminated by pressing the HLT key, adds a carriage-return to the line,
inserts the line into the message, sets the line pointer to the inserted line, and terminates the
d. An empty line, terminated by pressing the HLT key, terminates the subcommand.
If there is not sufficient memory available to insert the line of text, error
message No. 3 is printed. The line is not inserted into the message. The
subcommand is terminated.
