Loads a set of properties into the receiving Properties object from
source. The load source can be either the string name of a file or a stream object. Properties are read from the source as individual lines using linein() (
Section 5.2.4.13, “lineIn”). Blank lines and lines with a Rexx line comment ("--") as the first non-blank characters are ignored. Otherwise, the lines are assumed to be of the form "name=value" and are added to the receiver Properties value using name as the index for the value. Properties loaded from
source that have the same names as existing items will replace the current entries.
