5.1 Let's Get Past the Forinalities CP/M 3 User's Guide
This general form is called a file specification. A file specification names a particular
file or group of files in the directory of the on-line disk given by the drive
specifier. For example,
B:MYFILE.DAT
is a file specification that indicates drive B:, filename MYFILE, and filetype DAT. File
specificat'on is abbreviated to
filespec
in the command syntax statements.
Some CP/M 3 commands accept wildcards in the filename and filetype parts of the
command tall. For example,
B:MY*.A??
is a file specification with drive specifier B:, filename MY*, and filetype A??. This
ambiguous file specification might match several files in the directory.
Put together, the parts of a file specification are represented like this:
d:filename.typ;password
In the preceding form, d: represents the optional drive specifier, filename represents
the one- to eight-character filename, and typ represents the optional one- to threecharacter
filetype. The syntax descriptions in this section use the term filespec to
indicate any valid combination of the elements included in the file specification. The
following list shows valid combinations of the elements of a CP/M 3 file specification.
o filename
o filename.typ
o filename;password
o filename.typ;password
o d: filename
o d:filename.typ
o d:filename;password
o d: filename. typ;password
