/* The PUTF and RPRO fields in dbCommon are flags that indicate when a record
* is being processed as a result of an external put (i.e. some server process
* calling dbPutField()), ensuring that the record and its successors will
* eventually get processed even if they happen to be busy at the time of the
* put. From Base-3.16.2 and 7.0.2 the code ensures that all records downstream
* from the original are processed even if a busy asynchronous device appears
* in the processing chain (this breaks the chain in older versions).
*
* PUTF - This field is set in dbPutField() prior to it calling dbProcess().
* It is normally cleared at the end of processing in recGblFwdLink().
* It may also be cleared in dbProcess() if DISA==DISV (scan disabled),
* or by the processTarget() function below.
*
* If PUTF is TRUE before a call to dbProcess(prec), then after it returns
* either PACT is TRUE, or PUTF will be FALSE.
*
* RPRO - This field is set by dbPutField() or by the processTarget() function
* below when a record to be processed is found to be busy (PACT==1).
* It is normally cleared in recGblFwdLink() when the record is queued
* for re-processing, or in dbProcess() if DISA==DISV (scan disabled).
