Q1. Using EXFMT opcode or Read
Q2. READC is used for reading all changed records in subfile

Answer / syam

EXFMT = Write Screen + Read Screen
To read subfile use always READC

Answer / ravi

When you declare SFLNXTCHG in the DDS. You can use READC opcode to find the changed records in the subfile. The MDT will be ON on the changed record. Once you read the record, it changes to off. This is how system identifies the changed records sequentially.

Best example is do WRKMBRPDM, it is nothing but a subfile. You can see all source members in your source file. Correct?

Now, enter display (option 5 i guess?) on say 5 sources and press Enter, control goes to the fisrt source and press enter, control goes to the second source etc.. isn't it?

That is nothing but READC usage.

Answer / karthika

READC is an opcode that is applicable only for subfile.

This will read the record that was changed during the last
execution of the program and not all the changed records

suppose i i am changing / updating record of subfile and i want to change the record in reverse order . means i want to change the bottom record first and so on through readc . how i do it please any one explain .
