4.3.1 PATHNAME RESPONSES. The required response for many of the Emulator commands is a
standard DX 10 pathname. The pathname of a file is a concatenation of the volume name, the
directory levels (excluding VCA T ALOG) leading to the file, and the file name itself. Components of
the pathname are separated by periods. The volume name need not be included if the volume is the
system volume. The total length of a pathname must be 48 characters or less. The following are
examples of valid pathnames:
Volume name, directory name, directory name, file name:
VOL.DIR.DIR I .FILE
Directory name, directory name, file name (volume will be system disk):
.DIR.DIR I.FILE
Volume name, directory name:
VOL.DIR
Directory name, file name:
.DIR.FILE
A special form of pathname, called the $-option, is used by the Receive Printer Data (RPR) and
Receive Punch Data (RPU) commands. Any standard pathname can be used as a $-option
pathname by placing a S at the end of the pathname, e.g.,
Standard Pathname: $-option Pathname:
VOL.DIR.FILE VOL.DIR.FILES
During the c.peration of the Emulator, the S is assigned a consecutive number, 01 through 99 (or
some value less than 99 if the capacity of the device is exceeded), each time a file is received in the
queue containing the $-option pathname. In this way, multiple -files may be received without having
to issue multiple RPR or RPU commands.

For further information about pathnames, refer to the Model 990 Computer DXJO Operating
System Release 3 Reference Manual, Volume II, pan number 946250-9702.
4.3.2 SYNONYM RESPONSES. A string of one or more characters can be defined to substitute for
a pathname and used as a response to a prompting message. A synonym can represent an entire
pathname or a component of a pathname. Using the pathname VOL.DI RB.DI RC.FILE, synonyms
could be assigned as in the following:
Synonym

AB
ABC
ABCD
4-7
