Environment variables

Some IBM® MQ settings have traditionally been configured by using environment variables.

For compatibility with WebSphere MQ for HP NonStop Server V5.3, some of these environment variables are still supported by IBM MQ for HPE NonStop V8.1. However, all of these settings can also be configured by using runnscnf. Using runnscnf has the additional advantage that spelling of names and range of values are checked, so that the number of potential errors is reduced.
