     With DECC$EFS_CHARSET enabled, UNIX names can contain ODS-5
     extended characters. Support includes multiple dots and all ASCII
     characters in the range 0 to 255, except the following:

     <NUL>
     /         *
     "         ?

     Unless DECC$FILENAME_UNIX_ONLY is enabled, some characters can be
     interpreted as OpenVMS characters depending on context. They are:

     :         ^
     [         ;
     <

It is. :-)

Not my code that requires it. Somebody elses code that I am just using.
