ALLBASE/BRW JCWs for Year 2000

by Kelly Sznaider

Support Technology Lab

For year 2000 compliance, two JCWs were created in earlier versions of BRW. However,

the defaults of these JCWs have been changed as of version A.01.57.

As year 2000 rapidly approaches, it is strongly recommended to use four-digit years

instead of two-digits. If four-digit years are used in your ﬁles and databases, then these

BRW JCWs can be ignored.

The remainder of this article provides information about the BRW JCWs which support

the reading and writing of two-digit years. They describe how BRW should interpret these

years, as 1900 based or 2000 based. As of version A.01.57, the defaults are 2000 based

instead of 1900 based.

HP’s MM II customers using ALLBASE/BRW should review these JCWs carefully and

preset them accordingly.

This change in the product’s behavior is speciﬁc to ALLBASE/BRW, not BRW/V.

1. Set the JCWs in session mode and also, in BRWJOB/BRWJ000 for batch processing.

The JCWs will map ‘00’..’49’ to ‘2000’..’2049’ or to ‘1900’.. ‘1949’ depending upon the

settings. Two-digit years of ‘50’ to ‘99’ are mapped to ‘1950’..’1999’ regardless of the

setting of the JCWs.

2. If these JCWs are not set, then it is the same as setting these JCWs to 1. Setting these

JCWs to 1 (or not setting them) assumes two-digit years with the century as “20” (for

years ‘00’ to ‘49’ only). Setting the JCWs to 0 assumes two-digit years with the century

as “19”, which was the default prior to version A.01.56.

3. The JCWs can be set differently depending upon the desired results.

• ALLBASE/BRW versions A.01.56 and earlier set the JCWs as the following if not

speciﬁed:

BRWCENTURYROUNDING = 0

BRWUSERCENTURYROUNDING = 0

• As of version A.01.57, the JCWs are defaulted as:

BRWCENTURYROUNDING = 1

BRWUSERCENTURYROUNDING = 1

BRWCENTURYROUNDING

The following apply to BRWCENTURYROUNDING:

• If set to 1 (or not set), a date range of 1950 - 2049 is assumed for all two-digit years in

user parameters values, constants in calculated items and selection conditions, and in

data ﬁles.
