PAUSE
The PAUSE statement suspends program execution. While the program is
suspended, you can display and modify values of individual variables,
modify program lines, and execute commands.
Syntax
PAUSE [str_expr]
Parameters
str_expr String expression that the PAUSE statement displays
before suspending program execution.
A suspended program resumes execution when the CONTINUE command is
executed.
PAUSE cannot be a command. The following are the equivalent to a PAUSE
command:
* Control Y (if no ON HALT statement is active).
* Control Y twice in rapid succession (even if an ON HALT statement is
active).

In the above program, the program is paused at line 50, and the first two
MAT PRINT statements are executed. The program is then continued, and
pauses again at line 70. At that time, the third MAT PRINT is executed,
and lines 80 through 120 are added to the program. The program is then
continued to completion. After this last CONT command, the new lines
(80-120) are executed.
