To obtain process time of a sub-process would require the use of PM, and the
AIF procedure.  The parent process would also have to know when it is
appropriate to obtain the process time for a sub-process (which obviously
increases the complexity of the task...)
 
A much simplier approach would be to have each sub-process do a PROCTIME
before and again after the search, compute the difference and report it or
pass it back to the father (msg file possible).
 
When I've incorporated timing or debugging steps in code I've used a
compliler switch to enable/disable inclusion of the code as a part of a
conditional compilation.  You might consider this if you don't need this
data all the time.  When you're in full production you may not want to incur
the constant overhead associated with this data....
