Using the MVS modify command to change options

After the NPF FSS writer has been started, you can dynamically make changes by passing an options string with the MVS™ MODIFY command.

For example, if the FSS was defined as TCPFSS, at the operator console you can enter:

      F TCPFSS,ESTAE-SDUMP=NO

When using the MODIFY command, be aware of when the new option takes effect. Some options take effect immediately, others take effect on subsequent print jobs. Some options are captured when an FSA or device is started. In these cases, that FSA would have to be stopped and restarted to cause the new options to take effect.
