Development Tools and Utilities

When you are writing requester and server programs for your Pathway application, a

variety of program development tools and utilities are available to you. These tools and

utilities allow you to shorten the amount of time it takes to code, debug, and test your

programs.

Programming Languages and Related Tools

Tandem provides compilers that allow you to write application programs in a number of

programming languages, including C, C++, COBOL85, SCREEN COBOL, Pascal, the

Transaction Application Language (TAL), the Portable Transaction Application

Language (pTAL), FORTRAN, and Extended BASIC. In addition, the Crossref cross-

reference generator is available if you want to supplement the cross-reference listings

provided by the compilers.

The Inspect Symbolic Debugger

The Inspect product is the symbolic program debugging tool for Tandem NonStop

systems. You can use it interactively to examine and modify the execution of Guardian

processes (for example, Pathsend requesters and Pathway servers) as well as SCREEN

COBOL requesters. An online help facility is available for all Inspect commands and

topics.

Using the Inspect product in a Pathway environment requires the use of two terminals or

a terminal emulator with windowing capability. One terminal or window acts as the

application terminal, while the second terminal or window acts as a command or Inspect

terminal.

The Pathmaker Application Generator

The Pathmaker product helps you create Pathway applications consisting of requester

programs written in SCREEN COBOL and server programs written in C or COBOL85.

To create applications with the Pathmaker product, you:

•

Enter information about your application into a series of screen-based entry forms,

which the Pathmaker product then stores in a catalog

•

Use the Tandem text editor, TEDIT, to create source files containing C or COBOL85

service code

At your command, the Pathmaker product uses the information from the catalog and the

TEDIT file to generate SCREEN COBOL requester code, C or COBOL85 server code,

and command files to configure and start the finished Pathway environment for testing.

The Pathmaker product simplifies the creation of Pathway applications by:

•

Generating application code in a uniform structure for all requesters and servers, to

help simplify maintenance and modification

•

Producing program statements for tasks that are specific to the Pathway environment
