STOP statement

Syntax: STOP

Discussion: The STOP statement terminates a program and runs the QMONITOR program. There can be more than one STOP statement in a program.

Application note: The most common way to terminate a program is to run another program, such as a menu program, via the RUN statement.

The STOP statement is a runtime statement, as opposed to the END statement which is a compile-time statement indicating the physical end of the source program.


 READ (1,400) EXCP=1000
 1000    IF EXCP NE 33 STOP

In this example, the STOP statement is used in the exception routine at statement-label 1000. In this case, if the system variable EXCP does not equal 33 (which indicates that a record is extracted by another user), the program will stop executing.
