Debugger or Diagnostic Directories
When using 187Bug, you operate out of either the debugger 
directory or the diagnostic directory. 
You may switch between directories by using the Switch 
Directories (SD) command.
You may examine the commands in the current directory by using 
the Help (HE) command. 
Keyboard Control 
Because 187Bug is command-driven, it performs its various 
operations in response to user commands entered at the keyboard. 
When you enter a command, 187Bug executes the command and 
the prompt reappears. However, if you enter a command that 
causes execution of user target code (e.g., "GO"), then control may 
or may not return to 187Bug, depending on the outcome of the user 
program.
