The 3525 Card Punch. This punch is supported by QSAM and BSAM for
the same basic punch and stacker selection functions that are provided
for the 2540 punch. It is also supported as a SYSOUT device and, if the
read feature is present, as a SYSIN device. (RCE cannot be used in the
latter situation.) All optional 3525 features are also supported by the
Assembler Language and by all OS high-level languages except ALGOL. The
3525 can be used to perform the following functions:
• Punching only - Either EBCDIC or binary data can be punched, and
stacker selection is supported.
• Reading only - Includes support of Card Image, RCE, and stacker
selection as described for the 3505 read.er
• Printing only - programming is similar to that for a printer.
Functionally, a card is considered to be a page with 25 possible
print lines. Varying the stacker selected by programming is not
supported; however, all cards can
be
directed either to stacker 1
or to stacker 2.
• Interpreting only - This is actually a punch and print combination
in which the data punched is also printed on line 1 (first 64
characters) and line 3 (remaining 16 characters), as shown
previously in Figure 20.30.4.
• Any combination of reading, punching, and printing - The concept of
associated data sets is used for handling two or more operations on
the same card. A separate data set is defined by the user for each
function (read, print, or punch) to be performed. These data sets
are allocated to the same 3525 via the
00
job controt statement (AFF
parameter), and when macros are issued, a certain sequence must be
maintained. The advantage of this approach is that it is
transparent to all high-level languages and it provides device
independence. For example
g
a program written in a device-
independent manner designed to read, punch, and print using the 3525
can be executed using a tape unit, a direct access device, and a
printer for the three respective operations, if necessary, merely by
changing job control statements.
os
utilities that use QSAM or BSAM suppo~ the 3525 and its optional
features as described above. ASP and HASP II support the 3525 for the
same functions they provide for other card punches.
30:15 DOS VERSION! SUPPORT
DOS support of model-dependent features of a Model 1q5 opera~ing in
Be
mode is provided in DOS Version 3 (Releases 25 Extended and 26) and
in DOS version 4 (Release 27). Support of new Model 145 hardware
features and I/O devices as of DOS Version 4 is discussed below.
Features available in Version 4 but not in version 3 are identified.
DOS Version 4 support of RAS features is discussed in Section 50.
New instructions. Assembler

the-following new System/370 instructions so they can be used in user-
written Assembler Language programs:
