Temporarily stops program
execution.
Syntax
- 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 & |
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'
