Model Level

You can change the setting of a model value for your model by executing the Change Model Value (YCHGMDLVAL) command. Be sure to use YCHGMDLVAL, rather than the OS/400 command, Change Data Area (CHGDTAARA). Changing model values involves more than changing data areas; many internal model changes are made by YCHGMDLVAL.

You should always exit from your model entirely when changing model values. Although the command can appear to run successfully while you are in the model, there is no guarantee that a full update has taken place.

For more information on using the YCHGMDLVAL command, see the Command Reference.
