Please explain what you really want to do,

And why do you think that a panel will read the data ?
What is wrong with EXECIO ?

I think joyeeta paul wants to understand how to work with page up page down on a panel?

if yes.. then u need to use tables to display multiple page records in a panel.. table (tbcreate, tbadd, tbbottom, tbdispl etc..) will take care of page up page down...

let us know if this is ur doubt!!

ya i know the EXECIO command.i used that one in my rexx prog.but i want to see file records in a panel. actually i have one ps file with more than 1 line of records. now i want to display the records in a panel .so i need a loop to read the records one by one from the file.there will be a limit i.e. end of file.

So, you want to:

Read a record.
Display that record in a panel.
Presumably, wait for some user input, then move on or exit out.
Display the next record.
Continue on until EOF.

Is that about it?

no, all records will in same panel.all records will be displaying in the same panel line by line until end of file.this line by line thing should be in a loop as we use in EXECIO.

You can't read records within ISPF panel (unless you use EXECIO within *REXX within the panel, which is silly).

A dataset can be read using some programming language (to include REXX), and then its content is saved in variables. Then, you may use ISPF panel to display these variables.

I'm probably not the only one confused here. genesis786 has already mentioned using an ISPF Table and storing the records that way, then using a TBDISPL service to display the table in a panel. I'm puzzled as to why you wouldn't just use a BROWSE or EDIT, with or without a panel.

Otherwise, the only other option I can think of is a panel that uses a dynamic area.

Normally, you would just want to browse the dataset. Done!

But some datasets have records that are not best for browsing. The easiest is to read your raw data, convert / format into readable records and make a new report dataset and browse that. Still fairly simple. But you loop through your many records and processing them and when done, then do a single display.

Already suggested as a table display. You loop through your many records and processing them and when done, then do a single display. It is not clear why you want the display within a loop.

You can use the BRIF service (browse interface) to browse through your data, but much more complicated because you have to provide some assembler exits.

Using tables you can do something like this:

This is MYPANEL

actually my file is holding some pieces of code.if i select a certain condition the corresponding piece of code will be displaying in the panel.the code has more that one line.
here i think i can't use a table format. is there any other way to display the rec(code) in a panel? can anybody suggest me?
