e. Lines which consist of only carriage-returns are inserted into the memory as a SPACE
code, followed by a CR code.
f. The keystroke sequence for the INSERT subcommand is " b0lNSERTb0CR ".
g. The shortest acceptable form of the subcommand is 1.
h. Operator example: The operator has a paragraph to add at the end of a previously compos-
ed message. After moving the pointer to the last line of the message, the operator is ready to add
the new paragraph.
Inputs b0INSERTb 0CR and types in the new paragraph text and presses the HLT key.
None until after the subcommand is terminated; then the EDIT prompt sequence is issued:
The terminal adds the new paragraph to the end of the message.
This subcommand allows the operator to delete (erase) a specified number of lines from the
edited message, starting at the current line pointer. If the number of lines to be deleted is not
entered, it is assumed to be 1. If an " * " is specified, or the number of lines specified is greater
than the number of lines remaining in the message, the rest of the message is deleted.
a. At the completion of a delete, the line pointer is set either at the next line not deleted, or
at the new last line of the message.
b. If the message is empty after the deletion, error message No. 7 is printed.
c. If the message is not empty after the deletion, the line at the line pointer is printed.
d. If the number of lines specified is greater than 99 or is an alpha character, error message No.
10 is printed.
