I am aware of this but it does not fall into my "full scale" 
understanding of how it works and/or how to implement it.  Not too long 
ago I briefly spoke with a list member who does this so I opted to 
"bait" him into the conversation; or others that may have offered a full 
and accurate explanation on hat particular subject.

I did not pay too much attention to your filePro code, hate fpWeb and I 
was "told" not to touch the processing table (Linda I think ...), this 
was yours and/or two other very specific staff members to deal with ... 
in fact, I had to go out of my way to try to find ways to get around 
this processing table but it proved to be a grave error (I dropped the 
ball and I am no longer with the Company).

This could be a trap if not properly terminated, just like "gosubs".  It 
is a matter of programming techniques and/or approach to a problem.  
filePro, AFAIK, is not an OOP language nor it is a procedural language 
but the "call/chain" is the closest it will come to a "procedural" 
language ...the way I see it.

Again, I can see calling one or two tables but the use of "nested" and 
wonder about how deep you can go gives me pause and wonder why one would 
need more than two or three ... I have written very large and very 
complex filePro application and never needed more than one, perhaps 
because I adopted to the handicap back then.

Yes I have, and I can hold my own next to anyone ... but that does not 
mean I get the results in the exact same manner you would.
