The following are examples of running the script tcl_ins.d
|
|
|
|
Here it traces as Code/Tcl/func_slow.tcl executes.
|
|
|
|
# tcl_ins.d
|
|
Tracing... Hit Ctrl-C to end.

It is showing the instructions called by Tcl as the program executes. The
|
|
larger counts toward the bottom of the display are from the looping construct
|
|
used in Code/Tcl/func_slow.tcl.
|
|
|
|
Tracing the instructions is quite low-level and slow the target application
|
|
considerably and would probably be used only as a last resort if you have no
|
|
other indication of why CPUs are busy.
