Figure 61 shows the format of the Dispatcher TCB Modes report. This report is produced using the EXEC CICS® COLLECT STATISTICS DISPATCHER command. The statistics data is mapped by the DFHDSGDS DSECT. The field headings and contents are described in Table 185. In the Dispatcher TCB Modes report, some fields (for example, TCB Allocates) only apply to open TCB modes. The validity of these fields for each mode can only be determined once a TCB has been attached in that mode. Until the first TCB has been attached in that mode, the fields are marked 'N/A'. Once the first TCB has been attached in that mode, if it is not an open TCB mode, the field continues to be marked 'N/A'. If it is an open TCB mode, the field is given a value.
