logclose
Description
Closes the specified log and prevents further writing to that log until it is reopened.
Example 38. Log messages and display log content to the windows system
This example, using inline PIs, will write the words `hello' and 'world" to the log number 7 (LOG7), then display the content of LOG7 to a windows system pop up box:
The quick <?logwrite LOG7 hello> brown fox <?logwrite LOG7
world> jumps over a <?logopen LOG7 SYSTEM> lazy dog.
Putting an <?logclose> at the end of the line would close the log, thus preventing any more writing to it.

Additional Information
The logclose macro is identical in function to its processing instruction equivalent. Its purpose is to allow logs to be controlled through a script, instead of within a formatting operation. The use of the macro is completely interchangeable with the PI so, for example, it is possible to write to a log using the <?logwrite> PI, and close it via the logclose macro detailed here.
