TRACE REGISTERS
TRACE REGISTERS
The TRACE REGISTERS command displays TNS/R frames. For TNS/R frames,
Inspect displays the PC register in the normal Inspect form as a scope name and
offset. Inspect also displays the virtual frame pointer (VFP) for that frame.
Debugging at the TNS/R Native Machine Level
Inspect provides some functionality for examining the TNS/R machine state when
debugging native programs. For more information about debugging at the TNS/R
native machine level, see Section 15, Using Inspect on a TNS/R System, and the
Debug Manual.
