FILESPEC FORMAT
CP/M 3 identifies every file by its unique file specification,
which can consist of four parts: the drive specification, the
filename, the filetype and the password. The term "filespec"
indicates any valid combination of the four parts of a file
specification, all separated by their appropriate delimiters.
A colon must follow a drive letter. A period must precede a
filetype. A semicolon must precede a password.
The symbols and rules for the parts of a file
specification follow:
d: drivespec optional single alpha character (A-P)
filename filename 1-8 letters and/or numbers
typ filetype optional 0-3 letters and/or numbers
password password optional 0-8 letters and/or numbers
Valid combinations of the elements of a CP/M 3 file specification
are:
filename
d:filename
filename.typ
d:filename.typ
filename;password
d:filename;password
filename.typ;password
d:filename.typ;password
If you do not include a drive specifier, CP/M 3 automatically
uses the default drive.
Some CP/M 3 commands accept wildcard (* and ?) characters in the
filename and/or filetype parts of the command tail. A wildcard
in the command line can in one command reference many matching
files on the default or specified user number and drive. (See
Commands).
