8.3 Jasper Package Options

The following Java system properties can be set to control some features of the Jasper package:

se.sics.jasper.SICStus.debugLevel

This flag is unsupported.

You probably should not use it in production code. It may be removed or change meaning in future releases.

An integer, zero by default. If larger than zero, then some debug info is output to System.out. Larger values produce more info. The value of this flag can be set and read with SICStus.setDebugLevel() and SICStus.debugLevel():

% java -Dse.sics.jasper.SICStus.debugLevel=1 …

or, from Prolog:

jasper_initialize(
   ['-Dse.sics.jasper.SICStus.debugLevel=1'],
   JVM)
