Product Features

The large test field is supported under relational databases which support that type of data element. Large text fields are limited to 2000 characters (ASCII) data within the large test field. When these large text fields are combined with the multi line edit fields, you have an ideal place to store notes or comments in a table.

Multiple Collating Sequence Based on National Language

Allows sorting by various character sets.

Exit called Global or local LS

The CALLEXIT statement will return to the correct location. It does not need explicit directions to be programmed by the user.

Multi Lingual Support

The base PRO-IV product contains support for the forthcoming multi lingual translation utility. You can deploy your application in either multiple languages simultaneously or maintain a single code base with separate languages embedded in the applications code, and then extract them as single language versions or multiple language applications.

International Character Set Support (UTF-8 & UNICODE)

The PRO-IV kernel now supports data storage in UTF-8 code set format for those relational databases which support this mode. UTF-8 is designed to allow storage of mixed multiple non-English language character set support.

Variables in Screen Formats.

PRO-IV now supports variables in screen formats. This new functionality enables you to create screens that can be modified using logic.

Non Zero Special Check.

A new pre-redefined special check has been introduced, NONZERO. This special check ensures that input to a numeric field is not equal to zero.

Improved Oracle Performance

The new relational database interface supports Oracle, Ingress, Sybase and provides the framework for fast development and deployment of new relational database interfaces. This new interface has also allowed us to tune the speed and performance of the Oracle interface in several critical functional modes.

After Write No Error Logic - Specify the ID of a logic to be processed after a record is written without an error.

Before-Read Sort Logic - Specify the ID of a logic to be processed before a file is read during sort/select processing.

Display Logic - specify a logic to be processed prior to displaying the contents of a field. The purpose of this logic is to modify the display attributes.

EOD/CANCEL Logic - Specify the ID of the logic to be performed if EOD or CANCEL is pressed.

LS Entry Logic - Specify the ID of the logic to be performed each time the LS is entered.

Read Access Locked Logic - Specify the ID of the logic to be performed whenever an attempt to read a record fails because the record was locked.

Window Logic - Specify the ID of the logic to be performed after the window key was pressed but before executing the window LS.

PRO-IV Client Server Technology Applications Overview

PRO-IV client server is intended to provide you with a methodology whereby you can distribute processing between two machines that share relational database table structures. This database may be on either machine, and forms the basis of the client server command bridge.

The PRO-IV client application consists of a PRO-IV kernel that runs the primary functions. A primary function may be used to enter data, modify customer information etc. This application can be run as a PC application with a SQL NET connection to the host machine. If you wish to perform an update or sort, correlate or massage a large data set, you may wish to have this portion of the function execute on the host machine where UNIX power is available and network traffic is low.
