SRTSEQ/ALTSEQ in an

RPG

Program

versus

a

DDS

File

When

a

keyed

file

is

created

using

SRTSEQ

and

LANGID,

the

SRTSEQ spec

is

used when

comparing

character

keys

in the file during CHAIN,

SETLL,

READE

and READPE operations. You do not

have

to

specify

the

same,

or

SRTSEQ

value

when

creating

the

RPG

program

or module.

When a value for SRTSEQ is specified

on CRTBNDRPG or CRTRPGMOD, then all

character comparison operations in the

program

will

use

this

SRTSEQ.

Thi

including

key

fields,

fields

from

other

fields

declared

in

the

program.

You

should

decide

whether

to use SRTSEQ

for

your

RPG

program

based

you

want operations such as IFxx, COMP,

and

SORTA,

to

work

on

your

ch

data,

not

on

what

was specified

when

creating

your

files.
