Break event
Break event. The type of debug event that occurs when a breakpoint causes a program's
execution to halt.
Break location. The part of a breakpoint's definition that specifies where the breakpoint is
located.
Breakpoint. A location (or point) in a program where execution is to be suspended so that
you can then examine and perhaps modify the program’s state. You can set and clear
breakpoints with Inspect commands. In this manual, a breakpoint is assumed to be in
TNS memory unless the location is called a “TNS/R breakpoint.”
Breakpoint activation. The time at which program execution encounters a breakpoint.
Breakpoint activation results in a break event if the breakpoint has no conditions or if
its conditions are met.
Breakpoint definition. The time at which you set a breakpoint (using the BREAK
command).
Breakpoint list. The list of breakpoints defined in a program. When debugging several
programs concurrently, Inspect maintains a separate breakpoint list for each program.
Call history. The list of scope-unit activations (calls) displayed by the TRACE command.
TRACE orders this list from the most recent to the earliest call.
Clause. An extension to an Inspect command. All command clauses start with or include a
descriptive keyword that identifies the clause.
CISC. See complex instruction-set computing (CISC).
Code base. The address at which the code for a scope unit begins—not to be confused
with the primary entry point, which is the address at which execution of a scope unit
begins.
Code block. The smallest cluster of object code that BINDER can relocate separately from
the rest of the object code. BINDER code blocks and Inspect scope units are roughly
equivalent, but they are not interchangeable terms.
Code breakpoint. A breakpoint set at a code location.
Code location. A specific location within a program's object code. Inspect lets you define
code locations using source-language expressions and identifiers in addition to
machine-level addresses and offsets.
Code offset. An offset from a named code location. Code offsets are specified as a number
of code units.
Code unit. A measure of code. There are three code units: INSTRUCTION, STATEMENT,
and VERB.
