Limits and Ranges

The following limits exist for the Sybase file system:

Maximum number of columns per key: 16
Maximum number of columns: 250
Maximum number of bytes in a single row when using Acu4GL for Sybase: 1962

To achieve the same sort or retrieval sequence under Sybase as under the Vision file system, key fields that contain signed numeric data must be preceded by a BINARY directive.

Acu4GL for Sybase supports the data types shown below. When it’s creating tables, the following conversion rules are used, in the sequence shown:

COBOL	Sybase
DATE directive	DATETIME
BINARY directive	VARBINARY(n) (if SIZE < 255) IMAGE (if SIZE > 255)
VAR_LENGTH directive	VARCHAR(n) (if SIZE < 255)
Usage FLOAT	REAL (if SIZE = 4) FLOAT (if SIZE = 8)

Any other numeric usage:

PIC
9(n)V9(m)

SMALLINT (if m = 0 and n < 5)
INT (if m = 0 and n < 10)
DECIMAL(n + m, m)(otherwise)

Any other usage:

PIC
X(n)

CHAR(n) (if n < 255)
TEXT (if n > 255)

Other limits are described in Limits and Ranges of the ACUCOBOL-GT documentation.
