Kernel Debugger and Dump Formatter Command Reference

The Kernel Debugger and Dump Formatter share a common subset of commands which comprises the vast majority of the combined command set. The following symbols will be used to denote to which tool commands are applicable:

Dump Formatter

Kernel Debugger

References to some system control offsets blocks are made in the descriptions of the commands. For the sake of brevity, the ALLSTRICT version of the OS/2 WARP 3.0 kernel is assumed and in some cases the equivalent RETAIL and HSTRICT kernel offsets are given in parentheses. For example:

      JFN_pTable (PTDA +0x5b8 (H/R: +0x5b0))

The reader should refer to System Reference. for control block layouts of the ALLSTRICT, HSTRICT and RETAIL kernels for OS/2 WARP 3.0 and OS/2 2.11 kernels.

Commands are categorised into two classes:

Internal

Internal commands begin with an alphabetic character. They are control program independent in the sense that they relate only to the Intel 80x86 hardware architecture.
External
External commands are prefixed with a period. They relate to the software environment under analysis and are dependent on the data structures of the operating system environment.

Complex expressions may be used where substituted values are required. The rules governing expressions are described in The expression evaluator.
