VMS Pascal

Introduction:

VMS Pascal is a very powerful Pascal dialect.

Documention @ VSI:

• Reference Manual
• User Guide

My article:

VMS Pascal for C/Java/C# programmers gives a good overview for the developer with experience in some other common languages.

The followup VMS Pascal modernization show how to modernize VMS Pascal applications by better integrating them into larger IT environments.

Open source libraries:

I have created some Pascal wrappers for common C libraries and other potential useful stuff:

PCOMMON

some common definitions used by the rest (use this if you plan on using more than one of the rest from the same application)

PMySQL

wrapper for libmysql for access to MySQL databasesdd>

PSQLite

wrapper for SQLite C library for access to SQLIte databases

PBDB

wrapper for BDB library (only a small part of functionality)

PRedis

wrapper for HiRedis (Redis client library)

pJSON

wrapper for cJSON for parse and generate of JSON

psocket

wrapper for C socket library (text only)

PHTTP

wrapper for simple HTTP GET and POST requests and response reading (text only)

pSolr

Solr client API

PXMLRPC

wrapper for XMLRPC C library for calling XML-RPC web services

PSTOMP

wrapper for simple_stomp C library for access to any message queue with support for STOMP protocol

PKAFKA

wrapper for librdkafka library for access Kafka topics

PZMQ

wrapper for LIBZMQ (ZeroMQ client library)

VPUnit

very simple unit testing framework

The code is available here.
