Printer Output

The include file zunit.inc defines two units for printed output: IQPRNT and IQLOG.

• RULE: IQPRNT is reserved for very brief initialisation and termination summaries together with serious error messages. In an interactive session IQPRNT output is sent to the user's terminal and the idea is that it should contain just sufficient information to determine if the program is working correctly. We have to avoid sending so much that an important error message gets overlooked.

• RULE: IQLOG should be use for all printed output, including that sent to IQPRNT.
