2 Package: XWB - Kernel RPCBroker
3 Date Created: Sept 18, 1997 (Version 1.1)
4 Site Name: Oakland, OI Field Office, Dept of Veteran Affairs
5 Developers: Danila Manapsal, Don Craven, Joel Ivey
6 Description: Contains TRPCBroker and related components.
7 Current Release: Version 1.1 Patch 47 (Jun. 17, 2008)
8*************************************************************** }

10{**************************************************
11This is the hierarchy of things:
12 TRPCBroker contains
13 TParams, which contains
14 array of TParamRecord each of which contains
15 TMult
16
17v1.1*4 Silent Login changes (DCM) 10/22/98
18
191.1*6 Polling to support terminating arphaned server jobs. (P6)
20 == DPC 4/99
21
221.1*8 Check for Multi-Division users. (P8) - REM 7/13/99
23
241.1*13 More silent login code; deleted obsolete lines (DCM) 9/10/99 // p13
25LAST UPDATED: 5/24/2001 // p13 JLI
26
271.1*31 Added new read only property BrokerVersion to TRPCBroker which
28 should contain the version number for the RPCBroker
29 (or SharedRPCBroker) in use.
