VTAM control block ID codes

z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures
GC27-3667-00

You can identify certain VTAM® control block types in a storage dump by examining an identification code in the first byte of the control block (offset 0). The control block identification codes are shown in the following table. If codes are duplicate, use other means (such as the operating environment or the control block's context) to determine the type of control block.

Note: Internal codes that are used only by the product support organization to assist in internal flow diagnosis are not included in Table 1.
