Answer Posted / ravikant kumar
Which is a subfile record format keyword.If you perform read on the subfile, theinternal indicator MDT (modified data tag) is automatically set off by the system. If you again perform read on the same records, records won't be read.Because internal indicator MDT would be off. Hence you should be explicitly set on the MDT by SFLNXTCHG keyword.
