HP ALLBASE/BRW

by Kelly Sznaider

The last few revisions of HP ALLBASE/BRW have concentrated on the

integration of TurboIMAGE Third Party Indexing (TPI) with BRW.

BRW version A.01.54 introduced the support of TPI. In BRW version

A.01.55, more TPI enhancements were provided, as well as several

defect repairs. In the latest version of BRW, A.01.56, the main focus is a

TPI defect repair.

This version of HP ALLBASE/BRW, A.01.56, ﬁxes a TPI problem that

was introduced in version A.01.55. When using wildcard characters for

the Selection Set, the result shows that no records are found when data

actually exists. The TPI tracing mechanism shows the incorrect DBFIND

mode being used.

The other repair for version A.01.56, not related to TPI, corrects the

continuation spoolﬁle number when a report is split between multiple

spoolﬁles.

In the previous version of HP ALLBASE/BRW, A.01.55, three

enhancements and miscellaneous defect repairs were included. Among

these enhancements were two new JCWs: BRWSQLTIMEOUT and

BRWTPITRACE. BRWSQLTIMEOUT is given a value that is the number of

minutes the BRW SELECT statement waits before timing out. A

special value of 65535 causes BRW to wait indeﬁnitely. BRWTPITRACE

displays the TPI tracing information to $STDLIST. The third

enhancement in A.01.55 was to enhance the TPI selection algorithm. If

more than one BRW condition matches a TPI key, the BRW condition

that appears ﬁrst in the compiler listing is used. If two TPI keys start

with the same BRW condition, the longer key is used.
