/*
** Mimic BRW using An SQL stored procedure to build a recordset
** Build a workging table were oconv, sort is all done "server-side"
** So report can just have groups with Break-on, minimal chatter with OI.
**
** Note: RTI_XBAND_DATASOURCE_TEMPLATE is the basis for the program
** RTI_XBAND_GENPROC uses the template to generate the code
** RTI_XBAND_SUPPORT calls RTI_XBAND_GENPROC, compiles the source, loads it on stack like rlist
**
** The BRW, via NetOI / RunDotNet, calls RTI_XBAND_SUPPORT
**
** 03-27-13 rjc Created
** 06-27-18 rjc Support @mv in readnext / read, use onGosub
** 07-17-18 rjc Fixes for 10.0.0.3
** 12-05-19 rjc Add records_processed for 10.0.8
** 01-14-20 rjc use rlist_text_1 for row processed
