How do I read records from Subfile? what is the purpose of
READC explain with example?
Answer Posted / 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.
