Entering Debugger Command Lines
187Bug is command-driven and performs its various operations in
response to user commands entered at the keyboard. When the
debugger prompt
187-Bug>
appears on the terminal screen, then the debugger is ready to accept
commands.
Terminal Input/Output Control
As the command line is entered, it is stored in an internal buffer.
Execution begins only after the carriage return is entered, so that
you can correct entry errors, if necessary, using the control
characters described below.Note The presence of the upward caret ( ^ ) before a
character indicates that the Control (CTRL) key must
be held down while striking the character key.The cursor is backspaced to the beginning of the line.
^H (backspace) The cursor is moved back one position.
Delete
key
(delete) Performs the same function as ^H.
^D (redisplay) The entire command line as entered so far is
redisplayed on the following line.
^A (repeat) Repeats the previous line. This happens only at the
command line. The last line entered is redisplayed
but not executed. The cursor is positioned at the end
of the line. You may enter the line as is or you can add
more characters to it. You can edit the line by
backspacing and typing over old characters
