Depending on the value of a specified
variable, the process enters the debug
state. The variable is checked when
the breakpoint location is executed.
Set trace code
breakpoint
Debug lists the contents of specified
variables when the breakpoint location
is executed, then Debug resumes the
process.
Set execute code
breakpoint
Debug executes a specified string of
Debug commands when the
breakpoint location is executed.
Display breakpoints Debug displays all currently set code
and memory-access breakpoints for
the process being debugged.
BM Break on
memory
Set unconditional
memory-access
breakpoint
The process enters the debug state
when the breakpoint location is
accessed or modified.
Set conditional
memory-access
breakpoint
The process enters the debug state
depending on the value of a specified
variable. The variable is checked
when the breakpoint location is
accessed or modified.
Set trace memory-
