Why does sflnxtchg cause subfile Records to be changed?

This is because SFLNXTCHG caused the subfile records to be considered changed even though the workstation user did not change them. This allows the program to prohibit the workstation user from ignoring program-detected typing errors in subfile records.

What is sflnxtchg?

SFLNXTCHG is used in the subfile record format (SFL1) and conditioned with indicator 74. This is the indicator I will manipulate in my RPG program to mark subfile records that have been changed not by the user, but by my program. IBM i marks user changes automatically.

How does sflnxtchg handle typing errors?

If the program detects typing errors in the changed records, it can send update operations (UPDATE in RPG IV, REWRITE SUBFILE in COBOL) to the subfile records in error, setting indicators so that SFLNXTCHG is in effect during the update operations. These update operations are sent to the subfile record format.

What should I do if sflnxtchg is not specified?

If SFLNXTCHG is not specified, or is specified but not selected on the update operations to the subfile records, then the workstation user can press the Enter key instead of correcting the program-detected errors.
