SPECIFYING INPUT PARAMETERS4-52 XEROX DOCUPRINT 180 LPS PDL REFERENCEUNPACKThis parameter specifies the unpacking method of the input datawhen required.Syntax VOLUME UNPACK =option(s)Options Table 4-59 lists the parameter option(s) and definition(s).Points to noteNote the following when using the VOLUME command:• The character code assignment tables in appendix Csummarize the label specifications that are valid for each hosttype. If a selected HOST type is inconsistent with a selectedLABEL type, an error message is output by PDL, and a validlabel is automatically substituted. The LABEL parameter of theVOLUME command should not be coded in cases where it isnot appropriate for a particular host type.• A JDL is supplied with the printing system software to dump thecontents of a tape. Six standard tape formats may be dumpedwith this JDL (H6000 BCD, EBCDIC, ASCII, H2000 BCD, IBMBCD, UNIVAC FIELDATA). Check the listing of the DUMP.JSLfile 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 asCODE and UNPACK, in a user-coded JDL.• The MAXLAB and MINLAB on a 4 by 3 packed format tape arethe number of 6-bit bytes or characters in the tape blocks thatare treated as labels.• Input data is translated according to the CODE parameteroption selected on the VOLUME command. Any characterwhich is translated into an ASCII X’20’ is truncated after the lastsignificant (non-ASCII X’20’) character in the print record.• When running a CODE=NONE job with DUPLEX=YES andSHIFT=YES, MARGIN must be specified inm inches.For example:m=-V 2 -BEGIN-ALI + .01Table 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 orT4X3H2Specifies unpacking routines in which 6-bitcharacters are extracted and restored as 8-bit bytes.T4X3 is used primarily for Honeywell 6000 tapeswhile T4X3H2 is used for Honeywell 2000 tapes.UNIVAC Specifies an unpacking routine used for UNIVACtapes, although you can specify any of these routinesindependent of the HOST type.
