Table 20.30.2 compares the card print features offered by the 3525
Punch, the 551 Interpreter, and the 1404 Printer. Minimally, the card
print capability of the 3525 can be used for card interpreting functions
as a replacement for the 551. The 3525 offers increased printing
throughput ·over the 557 because online printing on the 3525 eliminates a
separate interpreting operation, multiple lines can be printed in one
pass of the card, and one or two lines can be printed faster than on a
551. In addition, data not punched in the card can be printed on the
3525. The 3525 with card-printing capability can also be used as an
alternative to 1404 cut-card printing operat.ions, which are not
supported by
as
or DOS data management.
ERROR RECOVERY PROCEDURES FOR THE 3505 AND 3525
Error recovery procedures have been redesigned to simplify, reduce,
or eliminate operator intervention. The amount of programmed error
recovery required is also reduced because of the many new functions
implemented in the control unit in the 3505. These include the
automatic feed retry and punch retry features already discussed.
The significant new feature of error recovery for these new units is
that if the control unit itself cannot correct a failure, it identifies
not only the error but the specific recovery action to be taken by the
error recovery procedure.
(ERP),
the operator, or both.
When a unit error (unit check in the. CSW) occurs, the control unit
presents four sense bytes to the ERP (instead of one as on the 2540).
The first two bytes specifically identify the error and indicate which
of three possible recovery actions the ERP is to take. The second two
sense bytes are provided for diagnostic purposes and are discussed under
"Maintenance
w •
The three programmed recovery actions defined are not
device dependent, so that the same
ERP
is used for both the 3505 and the
3525.
