Page B-6 GLOSSARY
WILDCARD A symbol that can represent a range of other characters. You might want
to think of it as a joker in a deck of cards. For example, if you wanted to
erase three files: FILE01.DAT, FILE02.DAT, and FILE03.DAT, you could
type all this:
ERASE FILE01.DAT
RETURN
ERASE FILE02.DAT
RETURN
ERASE FILE03.DAT
RETURN
or you could type:
ERASE FILE0?.DAT
RETURN
where the question mark symbol "?" represents all characters, or:
ERASE *.DAT
RETURN
where the asterisk represents all combinations of characters (in this
case, all filenames). Of course, you would not use the second command
if you had other .DAT files you wanted to keep.
WILDCARD FILE
COMMAND
SWITCHES
Wildcard file commands distinguish between two types of switches:
file
switches
and operation switches. If a file switch is directly after a file
specification, it affects only that file. For example:
ERASE MTDVR.M68,MTDVR.LIT/QUERY,MTDVR.OBJ
RETURN
tells ERASE to ask for confirmation before erasing MTDVR.LIT. It erases
the other two files without asking for confirmation.
An operation switch affects all files on the command line, no matter
where it is placed. For example, the /WIDE option with the DIR
command affects the directory display for all specified files, no matter
where it appears on the command line.
Wildcard file commands allow you to set the default switch by placing the
switch in front of a file specification. For example:
ERASE/Q MTDVR,MTDVR.OBJ/NOQ,SRCFIL.BAS
RETURN
tells ERASE to ask for confirmation before erasing the first and third files
specified on the command line.

mand switches and default switches.
