Debugging the Current Program
Pressing BREAK returns you to the Inspect prompt.
If you press the BREAK key when entering a command (even if you are on a
continuation line), Inspect retains the accumulated command list, except for commands
on the line that you were entering. However, Inspect does not interpret the command
list; instead, it prompts for another command. Consequently, if you find that you have
made a mistake in a line, you can use the FC command to correct all but the last input
line of the command list and then reissue it.
Debugging the Current Program
The basic debugging commands that Inspect offers affect only one program: the
current program. Table 3-1 lists the basic debugging commands that fall into three
categories:
Commands that control program execution
Commands that access program information
Commands that simplify program debugging
Caution. A COMMENT (“- -”) command causes Inspect to ignore any commands that follow it
in the command list.
