On the 3715 or 3717, if the second disk feature is in-
stalled, printing can automatically continue from disk
1 to disk 2. However, the following conditions must
exist in order for the printer to automatically
continue:
• The data set on disk 1 must be a continued data
set.
• The first valid data set label on disk 2 must
identify the continued data set.
• The diskette must be inserted in drive 2 prior
to the initiation of printing.
When the 3715 or 3717 completes printing the records
from disk 1, and with the preceding conditions
present, the printer automatically switches to disk 2
and continues printing the data set.
When the printing of the data set from disk 2 is
complete, the incomplete print
(J)
error is displayed
if the data set is continued on another diskette or
diskettes. The operator can then perform the
procedure to continue the print data set operation.
(Drive 1 or drive 1 and drive 2 can be loaded with
diskettes if appropriate.) This process continues
until the last record of the multivolume data set is
printed.
Note:
Deleted records are not printed in print data
set mode.
Print under search content mode - the records found
within the current data set under search on content
are printed.
The following keying sequence initiates the print
under search content operation:
• FUNCT SEL lower
• SEARCH CONTENT
• Search mask
• FUNCT SEL upper
• PRINT TO EOD
The operation starts with the currently displayed
record (or BOE record if printing operation is
selected from read index mode) and prints all
records that match the mask. When EOD is
reached, the 3741 returns to read index mode and
displays the label for the data set.

Notes:
1. Deleted records are not printed in print under search
content mode.
2. The R format control character is operational in
print under search content mode, except on 3713
printers with a maximum line length of 128
characters.
Print under search address mode - the record found
under search on address is printed.
The following keying sequence initiates the print
under search address operation:
• FUNCT SEL lower
• SEARCH RECORD ADDRESS
• Record address
• FUNCT SEL upper
• PRINT TO EOD
This printing operation prints the record at the
specified address. When the operation is complete,
the 3741 is in update mode with the record printed
remaining displayed.
Notes:
1. Deleted records are not printed in print under
search address mode.
2. The R format control character is operational in
print under search address mode, except on 3713
printers with a maximum line length of 128
~haracters.
Printer Formatting
The format of output on the printer can be controlled in
one of two ways:
1.
2.
Local format control-the location having the printer
can write printer format programs and load these
programs into the program level buffers of the 3741.
CPU format control-the transmitting station (usually
a central computer) can send printer control charac-
ters intermixed with data. The printer control
characters determine the format of the output.
