The approach used here to avoid looping can also be used within an subroutine.

Specifying a Return Point

in

the

ENDSR

Operation

When

using an INFSR or *PSSR error subroutine

in a main procedure, you

indicate

the

return

point

at

which the program will resume processing

one

of

the

following

as

the

Factor 2 entry of the ENDSR statement. T

be

a six-position character

field, literal, named constant, array ele

name

whose

value

specifies

one

of

the

following

return

points.

Note:

If the return points are specified

as literals, they must be

trophes

and

entered

in

uppercase

(for

example,

*DETL,

not

*detl).

are specified in fields or

array

elements,

the

value

must

be

the

field or array element.

*DETL

Continue at the beginning of detail lines.

*GETIN

Continue at the get input record routine.

*TOTC

Continue at the beginning of total calculations.

*TOTL

Continue at the beginning of total lines.

*OFL

Continue at the beginning of overflow lines.

*DETC

Continue at the beginning of detail

calculations.

*CANCL

Cancel the processing of the program.

the subroutine was called by the

EXSR

operation

and

Factor

control returns to the next sequential

instruction.

After the

ENDSR

operation

of

the INFSR or the *PSSR subroutine is run,

RPG

compiler resets the field or array element specified in Factor

Because Factor 2 is set to

blanks,

you

can

specify

the

return

poi

routine

that

is

best

suited

for

the

exception

that

occurred.

If

this

field

contains

blanks

at the end of the subroutine, the I

tion

handler

receives

control

following

the

running

of

the

subroutine,

u

INFSR

or

the

*PSSR

subroutine

was

called

by

the EXSR operation. If t

tine

was called by the EXSR

operation

and

Factor 2 of the ENDSR ope

blank, control returns to the

next

sequential

instruction

following

the

E

tion.

Note:

You cannot specify a factor

2

entry

for

an

ENDSR

in

a

subproc

want to resume processing in the subprocedure, you have to us

operation to a TAG in the

body

of

the

subprocedure.

Alternativ

code a

RETURN

operation

in

the

*PSSR.

The

subprocedure

will

then

to

the

caller.
