1.1 Welcome to Acu4GL
Welcome to Acu4GLTM! This User's Guide describes how the ACUCOBOLTM-GT programming language uses Acu4GL products to access information stored in
Oracle, Informix, Sybase, Microsoft SQL Server, DBMaker, and ODBC-compliant
relational database management systems (RDBMSs). It explains how to describe data
in your COBOL programs, and how to handle differences in the field names and
data types that are passed between COBOL and the database engine. Acu4GL is part
of the extendTM family of Acucorp solutions.
Note: Unless otherwise indicated, the references to "Windows" and "Windows NT" in
this manual denote all 32-bit versions of the Windows and Windows NT operating
systems. Those versions are: Windows 95, 98, and ME, Windows NT 4.0, and
Windows 2000. In those instances where it is necessary to make a distinction among
the individual versions of those operating systems, we refer to them by their
specific version numbers ("Windows 2000", "Windows NT 4.0", etc.).
Acucorp tested the Acu4GL Version 5.2 products with the following Relational
Database Management Systems:
| DBMaker
| Informix
|
| Microsoft SQL Server
| ODBC
|
| Oracle
| Sybase
|
As a result of our testing and according to general information received from
the makers of the RDBMS regarding upward compatibility of their product, we
believe the following to be accurate:
RDBMS
| Acu4GL Version 5.2 Tested with RDBMS Version
| Probable Compatibility with Acu4GL 5.2, Based on Vendor Information
(Client/Server may be used for connecting to other versions)
|
| DBMaker
| 3.0
| No others
|
| Informix
| 5.1, 7.2, 7.3
| Versions greater than 7.3
|
| Microsoft SQL Server
| 6.5, 7.0, 2000
| Versions greater than 6.5
|
| ODBC Specification
| 3.0
| Versions greater than 3.0
|
| Oracle
| 7.3.3, 8.0.x, and 8i
for UNIX and
Windows (32 and 64-bit)
| No others
|
| Sybase
| 11.x
| Versions greater than 11.x
|
Note: If the Windows machine that you are installing Acu4GL on has the version 8.x
Oracle client software installed, you will need to install some additional
software. Please see Appendix C, section C.2.1 "Windows Installation Steps for the Acu4GL for Oracle Product" for information on installing the additional software.
The essence of an Acu4GL product is that standard COBOL I/O statements are used to access databases. Acu4GL handles the translation between standard COBOL and the language that
the RDBMS understands.
There are special instructions and status messages that apply to each
individual RDBMS. These are included in the appendices of this User's Guide, with each particular RDBMS having an appendix dedicated to its own specific
information.
