UNIVAC SDF TAPE FORMAT
XEROX LASER PRINTING SYSTEMS TAPE FORMATS MANUAL 11-11
Appropriate JSL coding for Univac tapes
Use the following special guidelines when coding a JDE to handle a
Univac tape format:
• Univac data can be formatted in both Fieldata and ASCII codes
in the same file. To provide for easily managed logical
processing test criteria, all Univac Fieldata is first translated into
ASCII. Thus, when specifying CRITERIA tables for RSTACK,
DJDE prefixes, and other logical processing functions, the user
should define these search criteria with ASCII string tape.
• Some data blocks at the end of a file may have no valid data.
These blocks are identified with an O‘77’ in the first control byte
in the block. Delete any blocks of this type with the BDELETE
command to prevent any printing of transient data. This criteria
test must be coded in octal since this block is not yet translated.
• In the Univac format, the actual print data starts in the first byte
of each record. Therefore, change the DATA parameter for all
Univac JSLs to DATA = (0,132). Failure to specify the initial
value of zero normally results in the loss of the first byte of each
print record.
• Code the Setup string S in the print image control record as an
RSTACK report delimiter.
• When the FONTINDEX option is specified, the font index byte
should be located at the beginning of the record (since Fieldata
and ASCII records can be intermixed).
