PAUSE
Chapter 10 423
PAUSE
Temporarily stops program execution.
Syntax
PAUSE pause-code
pause-code is a character constant or a list of up to 5 digits.
Description
The PAUSE statement suspends program execution and prints a message, depending on
whether digits, characters, or nothing has been specified in the PAUSE statement:
• If digits, the message “PAUSE digits ” is written to standard error.
• If a character expression, the message “PAUSE character-expression ” is written to
standard error.
• If nothing appears after PAUSE, the word “PAUSE” is written to standard error.
After displaying the appropriate message, the PAUSE statement writes to standard output one
of two messages that give information on resuming the program. If the standard input device
is a terminal, the message is:
To resume program execution, type GO.
At this point the program is suspended and remains so until the operator types the word GO
and presses the Return key. The program will terminate if anything other than GO is entered.
If the standard input device is other than a terminal, the message is:
To resume execution, execute a kill -15 pid &
command
where pid is the unique process identification number of the suspended program. This
command can be issued at any terminal at which the user is logged in.
Examples
! Write ”PAUSE 7777” to standard error
PAUSE 7777
! Write ”PAUSE MOUNT TAPE” to standard error
PAUSE 'MOUNT TAPE'
