Whenever an out-of-line PERFORM statement is executed, control is transferred
to the first statement of the procedure named procedure-name-1. Control is
always returned to the statement following the PERFORM statement. The point
from which this control is returned is determined as follows:
- If procedure-name-1 is a paragraph name and procedure-name-2 is not specified,
the return is made after the execution of the last statement of the procedure-name-1
paragraph.
- If procedure-name-1 is a section name and procedure-name-2 is not specified,
the return is made after the execution of the last statement of the last paragraph
in the procedure-name-1 section.
- If procedure-name-2 is specified and it is a paragraph name, the return
is made after the execution of the last statement of the procedure-name-2
paragraph.
- If procedure-name-2 is specified and it is a section name, the return
is made after the execution of the last statement of the last paragraph in
the procedure-name-2 section.
The only necessary relationship between procedure-name-1 and procedure-name-2
is that a consecutive sequence of operations is executed, beginning at the
procedure named by procedure-name-1 and ending with the execution of the procedure
named by procedure-name-2.
