CRx entry for ADD, DELETE, or FIND control block

The correlate search control block (CR) trace record contains information about a control block add, delete, or find operation in the VTAM® control point (CP).

Byte (hex)

00–02

Record ID:

C"CRA" (CRADD):

Add control block

C"CRD" (CRDEL):

Delete control block

C"CRF" (CRFIND):

Find control block

03

Type code

0

Procedure-correlation identifier (PCID) only (6–F contain zeros)

1

PCID and modifier list (6–F contain the modifier list)

2

PCID and search number (6–7 contain the search number, 8–F contain zeros)

04

ID is the primary address space ID (ASID). This field is 0 if the ASID is greater than X'FF'.

05

Return code if specified; some FIND calls to this macro do not include a return code but use CORCB ADDR as a return code.

06–0F

• If type code = 0, this field is 0.
• If type code = 1, this field represents the PCID modifier list and is padded on the right with zeros. If search number correlation is used, this field may be 0.
• If type code = 2, this field represents the search number and is padded on the right with zeros.

10–13

Calling module's return address

14–1B

PCID of the search being correlated

1C–1F

Address of an ISTCORCB; bytes 4–7 of the ISTCORCB contain the address of the control block being correlated (LCB, SITCB). This field is 0 if the entry type is "CRF" and the control block was not found.
