Hi Friends,

I am trying to implement an asynchronous record, would like to support

this "put callback" feature.  From the documentation, it seems I have to do

the following:

1. set "pp(TRUE)" for the field the user is going to "caput"

2. make sure only call "recGblFwdLink" (within "process") when the action is

    finished, or use a BUSY record in the end of the FLNK chain such that it

    is "DONE" only when the action is finished.  -- during this process the PACT

    field of the original record can go up and down.

I have been playing with all these combinations, and by adding "-w **" after

the "caput -c", am getting inconsistent and unreliable results -- it either does

not work - calls back immediately, or waits unnecessarily long then calls back.

It rarely calls back right after the original record finishes processing and declares

the action is finished.  Guess I missed something.  Please spare a few moments

and advice on what exactly I need to do.

(We use 3.14.12-0.4.0, on linux machines).

Thank you very much, Best regards,

Dehong
