SPECIFYING INPUT PARAMETERS
4-52 XEROX DOCUPRINT 180 LPS PDL REFERENCE
UNPACK
This parameter specifies the unpacking method of the input data
when required.
Syntax VOLUME UNPACK =
option(s)
Options Table 4-59 lists the parameter option(s) and definition(s).
Points to note
Note the following when using the VOLUME command:
• The character code assignment tables in appendix C
summarize the label specifications that are valid for each host
type. If a selected HOST type is inconsistent with a selected
LABEL type, an error message is output by PDL, and a valid
label is automatically substituted. The LABEL parameter of the
VOLUME command should not be coded in cases where it is
not appropriate for a particular host type.
• A JDL is supplied with the printing system software to dump the
contents of a tape. Six standard tape formats may be dumped
with this JDL (H6000 BCD, EBCDIC, ASCII, H2000 BCD, IBM
BCD, UNIVAC FIELDATA). Check the listing of the DUMP.JSL
file to determine the appropriate JDE for the tape to be dumped.
Other tape formats may be dumped by specifying the host-type
(DUMP or OCTDUMP) and appropriate parameters, such as
CODE and UNPACK, in a user-coded JDL.
• The MAXLAB and MINLAB on a 4 by 3 packed format tape are
the number of 6-bit bytes or characters in the tape blocks that
are treated as labels.
• Input data is translated according to the CODE parameter
option selected on the VOLUME command. Any character
which is translated into an ASCII X’20’ is truncated after the last
significant (non-ASCII X’20’) character in the print record.
• When running a CODE=NONE job with DUPLEX=YES and
SHIFT=YES, MARGIN must be specified in
m
inches.
For example:
m
=-V
2
-BEGIN-ALI + .01
Table 4-59. UNPACK parameter option(s) and definition(s)
Option(s) Definition(s)
NONE Does not perform the unpacking operation.
The default is NONE.
T4X3 or
T4X3H2
Specifies unpacking routines in which 6-bit
characters are extracted and restored as 8-bit bytes.
T4X3 is used primarily for Honeywell 6000 tapes
while T4X3H2 is used for Honeywell 2000 tapes.
UNIVAC Specifies an unpacking routine used for UNIVAC
tapes, although you can specify any of these routines
independent of the HOST type.
