JRE options must be
enclosed in parentheses. If you issue JREOPTIONS options on the command
line, then you must put a backslash (\) before the open parenthesis
and close parenthesis, as shown in the examples below. If you specify
multiple JREOPTIONS options, then SAS appends JRE options to JRE options
that are currently defined. Incorrect JRE options are ignored.
