The CB command displays the connection block (CB) at the specified simple address or at the simple address pointed to by the ASD number. If the simple address is valid and the word at the simple address plus 1 is a valid CB identification word (TAG of 3 and string CB_ID2), DUMPANALYZER analyzes the memory area as a connection block.

An alternative to the CB command is the CB option of the MODE command. This option causes connection blocks to be analyzed automatically whenever you request a stack dump with the STACK command.

Syntax

── CB ─┬──────┬─<simple address>─┬─────────────────────────────────────┤
       ├─ AT ─┘                  │
       └─ VIA ──<ASD number>─────┘

Explanation

The following text describes the meaning of each construct. Refer to “Basic Constructs” earlier in this section for information about the <simple address> and the VIA <ASD number> constructs.

CB <simple address> CB AT <simple address>

Analyzes the connection block at the specified address.

CB VIA <ASD number>

Analyzes the connection block addressed through the specified ASD entry.

Example

The following example shows output from the CB command.
