We can handle this using physical file RRN value.When user
enters some options in the first page and takes a pagedown

Read the changes on the subfile using ReadC ie; read the
option entered for that record and save the physical file
RRN value for that record in a temporary file along with
option (You can get RRN value by declaring File information
data structure for that physical file)

When you load the records in the subroutine bfore writing
the values to subfile ,Chain the temporary file with RRN
value and if the RRn is present in the temporary file move
the corresponding option to the Subfile options.

Check this temporary file evrytime you load the records on
subfile and update this temporary file evry time there is a
chnage on the subfile options.

Clear the temporary file when the user confirms delete or
when user doesnt want to delete.

We can handle this using arrays. When user
enters some options in the first page and takes a pagedown
then read the changes on the sub-file using READC. first
validate the option, if entered options are valid then in
first array store the fields value (through which we can
identify record as unique in sub-file) and in second array
store the option.

Whenever load the sub-file, then first check if subfile
record is in array (with lookup), then write option equal
to second array value and clear the array element. else
display blank option.

Whenever user press enter (suppose user choose one option
in page one and another option on page 3) then process
option through array.

CEELOCT and CEEDATE are APIs that exist on the system.

You do not need to create them.

In essence, what the CL that I supplied does is:

1) Use the CEELOCT API to convert the current date to
lillian.
2) Then you add or subtract the number of days you need
from the lillian date.
3) Then you use CEEDATE to convert the new lillian date
back to the date format that you wish, in this case, I used
YYYYMMDD.

Current Local Time (CEELOCT), to convert a date to Julian
format. To create this
program, you must use the CRTBNDCL command alone or the
CRTCLMOD
command and the CRTPGM command together.
PGM
DCL &LILDATE *CHAR LEN(4)
DCL &PICTSTR *CHAR LEN(5) VALUE(YYDDD)
DCL &JULDATE *CHAR LEN(5)
DCL &SECONDS *CHAR 8 /* Seconds from CEELOCT */
DCL &GREG *CHAR 23 /* Gregorian date from CEELOCT */
/* */
CALLPRC PRC(CEELOCT) /* Get current date and time
*/ +
PARMS (&LILDATE) /* Date in Lilian format */ +
&SECONDS /* Seconds field will not
be used */
&GREG /* Gregorian field will
not be used */
*OMIT /* Omit feedback

are signalled

CALLPRC PRC(CEEDATE) +
PARMS (&LILDATE) /* Today’s date */ +
&PICTSTR /* How to format */ +
&JULDATE /* Julian date */ +

Answer / guest.

System will take care of it . You do not need to specify
anything for that. Until user does not press Enter key
ReadC won't detect any change record.

First build the file according to the Size/Page. On Page up
load it again . u do not need to worry about the option u
have entered on first page.

in which journalling which attributes are necessary??/
