block_spec

A block_spec identifies a block in the program being debugged.

block_name: Name of the block. See block_name.
%BLOCK: Represents the currently qualified block. See z/OS Debugger variables.
cu_spec: A valid compile unit specification; see cu_spec.

You can use block_name only for blocks known in the current enclave.

For C++ only:
- Block_spec must include the formal parameters for the function. The correct block qualification is:
```
int function(int, int) is function(int, int)
```
- Use Describe CUS to determine correct block_spec for blocks known in the current enclave.
