get current procedure from nested list

[David McFarlane]

Lisa,

This was rather too complex for me to read through, but I have just a 
couple of thoughts.

First, the .edat file already contains a Procedure column for each 
logging level, and the currently running Procedure name is always 
available as a Context attribute at runtime (e.g., 
c.GetAttrrib("Procedure")) , so I don't know why that does not 
already do what you ask.

Much more importantly, as a general rule, one should *not* run 
Procedures from nested Lists.  For all I know you have a good reason 
in this case, but I want to make sure to discourage newcomers from 
this bad habit.  Generally much more sound to run Procedures only 
from a main un-nested List, and use nested Lists only to supply 
values that will the be used by the Procedures named by the main 
List.  Typically, running Procedures from nested Lists is a sign that 
the programmer has not fully thought through the design, and 
untangling that will likely solve many problems besides the immediate 
one (but again, you may have a good reason in your particular case).

Regards,
