The drive specifier field specifies the drive where the file is located. The filename and
type fields identify the file. The password field specifies the password if a file is
password protected.
-ne drive, type, and password fields are optional, and the delimiters :.; are required
only when specifying their associated field. The drive specifier can be assigned a letter
from A to P where the actual drive letters supported on a given system are deter-
mined by the BIOS implementation. When the drive letter is not specified, the current
default drive is assumed.
The filename and password fields can contain one to eight non-delimiter charac-
ters. The filetype field can contain one to three non-delimiter characters. All three
fields are padded with blanks, if necessary. Omitting the optional type or password
fields implies a field specification of all blanks.
The CCP calls BDOS Function 152, Parse Filename, to parse file specifications
from a command line. Function 152 recognizes certain ASCII characters as valid
delimiters when it parses a file from a command line. The valid delimiters are shown
in Table 2-1.
