REXXTOOLS/MVS

 

Seamless Extensions of TSO/E REXX

The REXX programming language is widely used for Rapid Application Development, Decision support, Executive Information Systems, and Automation. REXX is easy to learn and maintain, almost self-documenting and very efficient. Programs built with REXX are simple to maintain when compared with COBOL, PL/1 and assembler.

 

REXXTOOLS/MVS adds access method interfaces, plus many REXX language extensions that greatly increase the functionality of the REXX language.

 

REXXTOOLS/MVS is a collection of interfaces and facilities designed to expand the range of applications that may be implemented in REXX.

Many of the REXXTOOLS functions and host commands provide access to vital system services and data stores.

 

REXXTOOLS manages the tedious details of storage allocation and data conversion, freeing the programmer to concentrate on the requirements of the application. Where necessary, REXXTOOLS maintains a task-level context between function calls and host commands. By doing so, it is able to conserve and reuse the system resources it allocates on the application's behalf. For example, system service modules such as IDCAMS, are loaded just once per MVS task. REXXTOOLS saves module addresses so that subsequent invocations proceed more quickly. For the DB2 interfaces, the amount of contextual information saved by REXXTOOLS is extensive, yielding a significant boost in application performance.

 

In addition to the system service interfaces, REXXTOOLS augments the data manipulation capabilities of the REXX language with functions, host commands, and utilities.

 

REXXTOOLS may be used in REXX/MVS (interpreted REXX) or REXX/370 (compiled REXX) programs. Please see "Sample Applications" for complete examples of REXXTOOLS programming.

What Can You Do With REXXTOOLS/MVS?

 

Perform Common Programming Tasks Quickly and Easily

REXXTOOLS/MVS can be used to perform many common programming tasks quickly and easily. For example, you can use it to:

 

1. Create Internet Applications
REXXTOOLS/MVS can be used in REXX-based CGI scripts for popular MVS-based web servers, including IBM's Internet Connection Secure Server (ICSSI).

In addition, REXXTOOLS can be used with the RXSOCKET function of IBM TCP/IP to create applications using Internet protocols.

 

2. Create Client/Server Applications
REXX and REXXTOOLS/MVS are fully integrated into ISPF. REXXTOOLS lets you build applications to display and share VSAM and DB2-hosted data in hours instead of weeks.

 

3. Create System Automation Applications
REXXTOOLS is used in all of the major MVS automations packages. In these environments, corporations are using REXXTOOLS to develop automated trouble ticketing, exception logging, and data warehouse applications.

 

4. Create Bridge Applications
REXXTOOLS is often used to bridge gaps between vendor products and in-house applications. Since it provides access to a wide range of data stores, REXXTOOLS has been used with vendor products as diverse as CA-Endevor and Soft Switch.

 

5. Perform Year 2000 and Euro Currency Conversions
The REXXTOOLS access methods, data conversion and formatting routines make quick work of file conversions.

 

6. Write Batch Reports
REXX and REXXTOOLS/MVS can be used in batch jobs and started tasks to produce ad hoc and production reporting job streams. The REXXTOOLS currency formatting routine, D2PIC, provides the REXX programmer with the same support for number formatting as is available in COBOL.

 

7. Improve System Performance
The highly efficient REXXTOOLS ALLOCATE command can be used to replace TSO ALLOCATESs in your logon execs. Corporations that have implemented this change report savings that can justify the cost of REXXTOOLS in a matter of months. The ALLOCATE has also been combined with the REXXTOOLS interpretive compiler to do dynamic allocations from COBOL programs.

 

8. Create Custom Utilities
Many corporations have found that REXXTOOLS can be used to augment, and in some cases replace, expensive ISV-supplied utilities. In particular, our customers tell us that report writing using the REXXTOOLS Dynamic DB2/SQL is, in most cases, easier and performs better than equivalent most high priced ISV utilities.
