Command lines may be recalled using the <Control>-U, <Control>-D and <Control>-R key sequences.
<Control>-U and <Control>-D cycle up and down through previous command lines. <Control>-R recalls
and executes the last command line.
dBUG is not case-sensitive. Commands may be entered either in uppercase or lowercase, depending upon
the user’s equipment and preference. Only symbol names require that the exact case be used.
Most commands can be recognized by using an abbreviated name. For instance, entering h is the same as
entering help. Thus, it is not necessary to type the entire command name.
The commands DI, GO, MD, STEP, and TRACE are used repeatedly when debugging. dBUG recognizes
this and allows for repeated execution of these commands with minimal typing. After a command is
entered, press the <Return> or <Enter> key to invoke the command again. The command is executed as if
no command line parameters were provided.
