the backup’s processor is operable, the fault-tolerant facility re-creates the backup process
immediately. If the backup’s processor is inoperable, the fault-tolerant facility re-creates the
backup process when backup’s processor becomes operable.
• What Fault-Tolerant Facility Checkpoints
The fault-tolerant facility checkpoints the global-data portion of the globals-heap segment, the
main stack, and all open files when the STARTBACKUP statement is executed; however, your
program must contain a CHECKPOINT statement to verify the creation of a backup process
and to establish a valid takeover point in the program code (rather than in the run-time library).
STOP
STOP halts the execution of a run unit, either permanently or only to display a message.
NOTE: The 1985 COBOL standard classifies the latter use as obsolete, so you are advised not
to use it.
RUN
halts the execution of a run unit and transfers control to the operating system, closing any open
files.
message
NOTE: The 1985 COBOL standard classifies message as obsolete, so you are advised not
to use it. Instead, use a DISPLAY statement followed by an ACCEPT statement.
is a nonnumeric literal string. Execution stops temporarily and message is sent to the home
terminal. When any response or carriage return is entered, execution resumes.
The routine COBOL85^COMPLETION or COBOL_COMPLETION_ provides the application program
a means of reporting a completion code to the operating environment and terminating execution.
This statement suspends processing until the home terminal sends a carriage return:
STOP "Press Return to show you are out there.".
This sequence of statements is equivalent:
DISPLAY "Press Return to show you are out there.".
ACCEPT USER-REPLY.
STRING
STRING combines some or all the characters from two or more data items into one other data item.
