DIR is a version of DIRECT with "my new SCAN//WILD" which fully
supports pathological names. DIR is basically "plug-compatible"
with DIRECT. There are some minor differences (in the formatting
of DECtape and TMPCOR directories primarily), and some new
features./L
/L
DIR should fully support pathological names in all possible
constructs (e.g., "A:B 'NOT' X:Y"), including full wildcarding./L
/L
DIR supports device wildcarding (e.g., DSK?:)./L
/L
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)./L
/L
DIR (i.e., SCAN//WILD) has 8 new file expression operators. The
current list of operators is:/l
/l
	AND		Match if both simple specs match/l
	OR		Match if either simple spec matches/l
	NOT		Match if first spec but not second spec/l
/l
	IFAND		Match if secondary file exists/l
	IFNOT		Match if secondary file doesn't exist/l
	IFSAME		Match if secondary file is the same/l
	IFDIFFERENT	Match if secondary file is different/l
	IFOLDER		Match if secondary file is newer/l
	IFNEWER		Match if secondary file is older/l
	IFBIGGER	Match if secondary file is smaller/l
	IFSMALLER	Match if secondary file is newer/l
/l
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 on SYS:)./L
/L
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 appropriate). Yes friends and neighbors, you can now use
//CHECKSUM etc. on DECtape and TMPCOR! You can even use //INDIRECT!/l
/l
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.
