GOBACK Statement
The GOBACK statement is an HP extension to the ANSI COBOL standard.
The GOBACK statement marks the logical end of a program.
Syntax
GOBACK
Description
The GOBACK statement must be the only statement in a sentence. If used
in a series of imperative statements, it must be the last statement in
the series.
If a GOBACK statement is encountered in a called program, control returns
to the statement in the calling program immediately following the CALL
statement that initiated the called program. Thus, in a subprogram, the
GOBACK statement acts in the same way as an EXIT PROGRAM statement.
If a GOBACK statement is used in a main program, it is equivalent to a
STOP RUN statement. Thus, it indicates the logical end of the run unit,
and control is passed to the operating system.
Table 11-2 shows the relationship between the EXIT PROGRAM, STOP RUN,
and GOBACK statements.
