COBOL Support

Pervasive.SQL 9 provides the following support for COBOL applications:

SQL Enhanced Access

The Pervasive.SQL relational interface has been enhanced to include support for COBOL OCCURS constructs, partial REDEFINES, and variable record layouts. No changes are required to your COBOL application to take advantage of the SQL enhanced access.

You enable SQL access by describing the application's understanding of data to the Pervasive.SQL relational interface. In developer's terms, you define the metadata to the relational interface.

Refer to the chapter SQL Access for COBOL Applications in SQL Engine Reference for a complete discussion of how to take advantage of the SQL enhanced access.

Shifted and Unshifted Sign Value for NUMERIC Data Types

Each digit of a NUMERIC data type occupies one byte. The rightmost byte of the number includes an embedded sign with an EBCDIC value. By default, the sign value for positive NUMERIC data types is an unsigned numeric number.

You may now specify that you want to shift the value of the sign for positive NUMERIC data types.

See NUMERIC in SQL Engine Reference for a complete discussion of this feature.
