ICL 2900 VME/B TAPE FORMAT
XEROX LASER PRINTING SYSTEMS TAPE FORMATS MANUAL 16-3
Each user record can contain zero to four format effectors. The
following table (table 16-1, “Format effector interpretation”) outlines
the action taken depending on the format effectors:
Normal format effectors
Normal format effectors are one- or two-byte codes that may only
appear and begin in the first four bytes of a record. They are
composed of any combination of the following:
X‘22nn’ is used to space to line number ‘nn’ relative to Top-of-Form.
Line numbers must be greater than or equal to one, and cannot
exceed 255. If ‘nn’ is less than or equal to the current line number, a
space to line ‘nn’ on the next page occurs. If X‘21nn’ causes BOF to
be encountered (i.e., line ‘nn’ is greater that BOF minus TOF), the
space is processed as IGN. To process X‘0C’ and X‘2200’ properly,
channel 1 must be assigned a line number by the user; otherwise, a
print-and-space-one carriage control is substituted.
Table 16-1. Format effector interpretation
Formal effector Action
No format effectors or all
FEs are filler
Carriage control action is space-one-
and-print.
Multiple FEs Processed left to right. All carriage
control action occurs prior to printing.
Multiple FEs causing
page skips (within a
record or in consecutive
records)
Processed as ADVTAPE = YES*
First FE in report INITIAL = BOF*
All FEs causing bottom-
of-form to be encountered
(except X‘2200’ and
X‘0C’)
Processed as IGN*
* See PCC command in Printing System Reference Manual for
interpretation.
