The WRITE command saves any configuration changes made during the ctl session back to the source from which they were read. This is usually the PDE Control GDO, if ctl was started without the -file option.


{ WRITE | WR }

Usage Notes

The write command does not cause ctl to exit.

Because different users may be modifying the PDE control settings at the same time, ctl merges only the changed settings from the current ctl session to the PDE Control GDO. This minimizes the chances that concurrent users will overwrite each others’ changes.

If no changes have been made during the current ctl session, issuing a write command does nothing.
