VMS Help server Bugs

• The keyword search works fine on any number of levels down, but then the generic daemon doesn't know how deep the server went, so anchor names lack the intermediate levels. Solution : generate anchor names relative to the input path (before '?').
• DANGER : Attempts to access VMS topics with a weird name like ":=" will crash the server because VMS will try to create a .HLP file with an invalid file specification due to these special characters. Solution : Make a good escaping system (that works with VMS and Un*x styles as well). Crude and bulletproof solution : Ignore any offending topic name !
• Reference to another help library through @ will only search SYS$HELP for the corresponding .HLB file.
• We need an overview page that lists all help libraries available.
