Control block fields applicable for TESTCB

The field names shown in the first column of Table 1 are the values that can be coded for the field name operand of the TESTCB macroinstruction. The second column indicates the number of bytes that each field occupies. No lengths are shown for fields that can only be tested using fixed values (for example, MACRF=LOGON or CONTROL=QEC).
