Chapter 2. Using CMFMON’s Online Facility 29
Displaying Deltas and Totals
Seven CMFMON screens contain pairs of fields that present the same data from different
points of view: one field in total mode and the other in delta mode.
Total and delta mode behave slightly differently, depending on the screen at which you are
looking. The following table explains these differences.
To enter delta mode, in the COMMAND field, type DElta. To enter total mode, type DElta
OFF
.
The default for all screens is total mode. If you are in delta mode when you exit a screen, total
mode is immediately restored.
