vms.c Igor Mandrichenko and others
This file contains routines to extract VMS file attributes from a zipfile
extra field and create a file with these attributes. The code was almost
entirely written by Igor, with a couple of routines by GRR and lots of
modifications and fixes by Christian Spieler.
Contains: check_format()
open_outfile()
find_vms_attrs()
flush()
close_outfile()
defer_dir_attribs()
set_direc_attribs()
dos_to_unix_time() (TIMESTAMP only)
stamp_file() (TIMESTAMP only)
vms_msg_text()
do_wild()
mapattr()
mapname()
checkdir()
check_for_newer()
return_VMS
screensize()
screenlinewrap()
version()
