Introduction to MVME187Bug

Debugger or Diagnostic Directories

When using 187Bug, you operate out of either the debugger directory or the diagnostic directory.

	If you are in...	With the	You have available...
	If you are in...	prompt...	You have available...
		prompt...

	The debugger directory	187-Bug>	All of the debugger
			commands

	The diagnostic directory	187-Diag>	All of the diagnostic
			commands as well as all
			of the debugger
			commands

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.
