DIR is a version of DIRECT with "my new SCAN/WILD" which fully sup-
ports pathological names. DIR is basically "plug-compatible" with DI-
RECT. There are some minor differences (in the formatting of DECtape
and TMPCOR directories primarily), and some new features.
DIR should fully support pathological names in all possible constructs
(e.g., "A:B 'NOT' X:Y"), including full wildcarding.
DIR supports device wildcarding (e.g., DSK?:).
DIR supports node wildcarding (e.g., KL*_), although trying to access
any remote node will basically win you no more than an error message
(but it can be fun to watch it try).
DIR (i.e., SCAN/WILD) has 8 new file expression operators. The current
list of operators is:
AND Match if both simple specs match
OR Match if either simple spec matches
NOT Match if first spec but not second spec
IFAND Match if secondary file exists
IFNOT Match if secondary file doesn't exist
IFSAME Match if secondary file is the same
IFDIFFERENT Match if secondary file is different
IFOLDER Match if secondary file is newer
IFNEWER Match if secondary file is older
IFBIGGER Match if secondary file is smaller
IFSMALLER Match if secondary file is newer
For example, "*.* 'IFAND' SYS:" selects all your files (first spec
defaults to "DSK:[-]") which also exist on SYS: (defaults to *.*). "*
.* 'IFSAME' SYS:" operates in a similar manner, but the extant file on
SYS: must also be the same length, logical creation date/time, and the
same I/O mode. "*.* 'IFBIGGER' SYS:" would match any files which exist
on SYS: and are smaller than your counterpart file. The last five
operators are considered "successful" if the secondary file doesn't
exist (i.e., "BLAH.BAR 'IFBIGGER' SYS:" wins if the file doesn't exist
DECtape and TMPCOR directories are now considered "normal" directory
listings and are handled in much the same way as disk listings. To get
an "olde fashioned" listing, use the /DTA or /TMPCOR switch (as appro-
priate). Yes friends and neighbors, you can now use /CHECKSUM etc. on
DECtape and TMPCOR! You can even use /INDIRECT!
The more intrepid user is referred to the NFT manual (DOC:NFT.MAN)
appendices for a more detailed definition of some of the new aspects
of DIR in regard to file specifications, switches, and so on.
