1.1 timbl 7: **
8: ** This is unix-specific code in general, with some VMS bits.
1.8 timbl 9: ** These are routines for file access used by browsers.
1.1 timbl 10: **
11: ** History:
12: ** Feb 91 Written Tim Berners-Lee CERN/CN
13: ** Apr 91 vms-vms access included using DECnet syntax
14: ** 26 Jun 92 (JFG) When running over DECnet, suppressed FTP.
15: ** Fixed access bug for relative names on VMS.
1.28 duns 16: ** Sep 93 (MD) Access to VMS files allows sharing.
17: ** 15 Nov 93 (MD) Moved HTVMSname to HTVMSUTILS.C
1.52 duns 18: ** 22 Feb 94 (MD) Excluded two routines if we are not READING directories
1.61 frystyk 19: ** 18 May 94 (HF) Directory stuff removed and stream handling updated,
20: ** error messages introduced etc.
1.120 frystyk 21: ** HFN Separated transport
1.1 timbl 22: **
23: ** Bugs:
1.2 timbl 24: ** FTP: Cannot access VMS files from a unix machine.
25: ** How can we know that the
1.1 timbl 26: ** target machine runs VMS?
