Print image control record
The print image control record (type O'60') is also processed. It
consists of strings of commands with letter identifiers. The identifiers
which are recognized and processed by the Xerox/OSS are H, L, S,
and M. A period separates the command strings within the print
image control record. Any identifiers other than H, L, S, and M are
bypassed.
Heading string “H”
The string “H, options, page, text” causes the heading insertion and
automatic pagination by the Xerox/OSS. The options in the “H” string
are “N” for no heading printing, or “X” for page numbering and date
print suppression.
The page parameter gives the beginning page number for the report.
If the page number is not given, page numbering starts at page 1.
The text is a message of up to 96 characters which is printed two
lines above the given top-of-form line number, followed by automatic
spacing down to the top-of-form (TOF). Therefore, there is a Xerox/
OSS generated minimum of one blank line between the heading and
the first print line of the page. Details of processing the “H” string are
summarized below.
• No page numbering or heading is printed if a top-of-form value
is specified, either in the JDE or via the “M” string (which does
not allow two extra lines above it). In other words, the smallest
TOF value that allows page heading and/or numbering is 3.
• If both page heading and numbering are requested, the
heading starts at the left page margin; at position (left margin +
96 + 1), the word “DATE” appears with the date from the label.
“PAGE” is then concatenated to the heading line followed by a
page value of up to five digits.
If a left margin, as specified in the offset part of the JDE
command DATA (offset, length) does not allow sufficient
characters for the full heading line, the line is truncated from the
right margin, as necessary, to be equal to the length.
• If no page heading or page numbering is requested, the space
normally occupied by the field not selected is blank filled.
• If a page number initialization value is not given in the “H”
string, then 1 is used as the base page number value. As this
may give undesirable results from file to file, the user is
encouraged always to specify an initial page number in the “H”
string.
• The page number maintained and incremented by the Xerox/
OSS never exceeds 65,536. If incrementing continues, the
page number returns to 1.
• Within a single report, the page number continues to be
incremented for every page whenever the “H,N” option is in
effect, even though the header record is suppressed. If page
number printing is later turned back on by a subsequent “H”
command in the same report (without specifying a starting page
number), the printed page number includes the counts for all
intervening pages.
