Syntax of Low-Level Command Elements

Low-level Inspect command syntax is based on the syntax of Debug commands.

Inspect, however, allows symbolic references to code or data blocks in the break and

clear commands. Inspect supports Debug syntax for referencing specific code and

library segments in a multiple code segment program.

For a detailed syntax description of each of the low-level Inspect commands, use the

low-level Inspect HELP command.

Symbolic References

In the B (break) and C (clear) commands, low-level Inspect allows symbolic references

to a procedure name or a data block name:

B #block-name + nnnn

C #block-name + nnnn

where nnnn is the offset in words from block-name.

These symbolic references allow you to use a compilation listing without a load map to

determine the program-relative address of the breakpoint.

No other symbolic references can be used in the low-level Inspect command syntax.

Multiple Code Segment Programs

For multiple code segment programs, you must specify the code segment where the

address is located, in addition to the address. To specify a code segment, use the

following address modes:

{ UC | UL } [ .segment-number, ]

UC indicates that the address is in the user code space. UL indicates that the

address is in the user library space. Segment-number defines the particular code

segment within the user space; it must be a number in the range zero through 31

decimal. If you omit the segment number, Inspect uses zero.

indicates an address in the current code segment (user code space or user library

space).

For example, if #block-name is the name of a procedure in the first code segment of

the user code space, the command to set a breakpoint at this location has the format:

B UC.1, #block-name + nnnn

In a multiple code segment program, if you specify a code block name and you omit

the address mode, Inspect assumes the code segment to be the same as that of the
