Returns .true if the file system is case-sensitive. Otherwise returns .false.

On Unix-like systems where both case-sensitive and case-insensitive file systems may be mounted, this method returns .true if the file system root "/" is case-sensitive, and otherwise .false.

See also File class method isCaseSensitive which returns the same information.

say .RexxInfo~caseSensitiveFiles    -- 0 /* e. g. Windows */
