While navigating the trace table, display the data values that were captured as each statement was executed, if data monitoring is active. If the AUTOKEEP display is ON, the past data values associated with an executed statement automatically appear in the Keep window when the statement is displayed. In addition, use the DISPLAY, KEEP, and CORE commands to display past data values for any data item or COBOL language area (for example, TGT). However, these values are protected and, therefore, cannot be updated while viewing past data values.
In general, past data values are not captured for database areas or CICS task areas. However, a few of these areas, such as DFHEIBLK or SQLCA, are defined within the COBOL program and, therefore, reside in COBOL storage. For these areas, display past data values by specifying the data name defined in the COBOL program. If the CORE keyword is used (for example, CORE=EIB), current data values are displayed.
