Display CSECT Activity Locations

The Histogram panel shows the activity that is associated with a CSECT. A CSECT is divided into segments of a specified size in bytes, and the activity detected in each segment displays. To view activity locations:

Use either the Histogram or the Normalized Histogram line command.
- If you use the H line command, the values displayed in Histogram add up to the value of the selected CSECT (from the Totl% field).
- If you use the NH line command, the values displayed in Histogram add up to 100 percent.

Press Enter.

The Histogram panel displays:

Specify Histogram Group Size

The group size defines the resolution of the histogram. The initial size is set by using the Instruction group field of the Profile Parameters panel (see the Installation Guide). The default value is 32 bytes.

To change the value of the group size, type over the existing value and press Enter. The minimum size accepted is 2 bytes.
Specify 2 in the GROUP field to analyze execution at the lowest possible level.

If the source code for the program is registered with CA Mainframe Application Tuner, or if dynamic registration support is enabled, specify STMT in the Group field to display the verb that is associated with the statement, as shown next.
