What I meant to say was I don’t update Join files Tom does.

Join files are not updatable.

…until V5R4 with INSTEAD OF triggers. (At least, I think it was V5R4.)

You can use the logical file, do two reads then show screen.

Since you want data from both files at the same time, you might be better off with a join logical file. Issue – Join files are not updatable.

It’s taking all of the records in the two files and sorting them on the keys

R test1
K KEYFLD1
K KEYFLD2
K *NOKEY
R TEST2
K KFLD1
K KFLD2
K KFLD3

If this doesn’t work for you show use some sample data in the order you want it marking each rows source and field names.

i don’t want to change order of record… i want to change the order of file in LF — but the order of data in the logical file isn’t based on records it’s based on keys. It’s taking all of the records in the two files and sorting them on the keys.

That requires a change to the keys in the logical file
file 1
Key 1.1
Key 1.2
file 2
Key 2.1
Key 2.2
Key 2.3 <– add another key
if key 1.1 = 2.1 and 1.2 = 2.2 the record from file1 will be before record from file2 because key 2.3 > nothing
At least that’s the way i remember it, you can research it and tell me how it goes.
