-openFile:pathName withMode:openModeSymbol attributes:attributeSpec
-    "open a file, return an os specific fileHandle.
-     openmode is a symbol defining the way to open
-     valid modes are:
-        #read
-        #write
-        #readWrite
-        #appendWrite
-        #appendReadWrite
-        #createWrite
-        #createReadWrite
-
-     attributeSpec is an additional argument, currently only used with VMS
-     - it allows a file to be created as fixedRecord, variableRecord, streamLF, streamCR, ...
-
-     In VMS, if nonNil, it must consist of an array of strings (max:10), giving additional
-     attributes (see fopen description).
-     Passing a nil specifies the default format (streamLF) - ST/X always invokes this with nil.
-     This argument is ignored in UNIX & MSDOS systems.
-
-     This is a private entry, but maybe useful to open/create a file in a special mode,
-     which is proprietrary to the operatingSystem."
