OS/360 RELEASE 21.6 SCHEDULED FOR SUMMER RECESS
Implementation of Release 21.6 of OS/360 is currently scheduled for
the week of June 25 - 20, 1973. This weec'V falls in the break between
Quarters IV and I and has been chosen to minimize possible impact on class
work or scheduled research computing.
No changes will be made during Quarter IV; the present version will
continue as the production system. Release 21 will be the last official
IBM version of OS/360.
Each new release of an operating system offers operational improve-
ments, corrections to many known errors, functional enhancements, new
capability, etc. Desirable as these improvements may be they are weighed
against the possible disruptive effect, albeit temporary, on some users.
Sometimes we have skipped releases because the benefits have been marginal
at NPS. Of course, IBM's software maintenance policy also adds pressure
to keep "up-to-date". They generally continue to provide maintenance
support for the (n-l)th release for 6 months after the date of the an-
nouncement of the n-th release.
Our review of the Release 21.6 system suggests very few, if any, user
programs should be affected. However, we are delaying its implementation
until the summer break and are offering users the opportunity to pre-test
their jobs long before the Release 21 introduction. If you want to assure
yourself that your program(s) will run with no problems under 21.6, please
contact Mr. Edward Ward (In-132, Ext. 2796).
CP/CMS TIME-SHARING NOTES
1) PL/I and SCRIPT Not Available
PL/I is no longer supported under CMS. Use of PL/I has been found
to seriously affect the response time of the CP/CMS system degrading
service to all terminal users. SCRIPT, which has not been officially
supported at NPS since January 1971 has also been withdrawn from the
system.

2) FORTRAN Subroutine Name Trap
Under CMS, main FORTRAN programs and subroutines can be combined
in one source file and this file used as input to the FORTRAN compiler.
Alternatively, the subroutines can be entered as distinct files and
compiled separately. The object program is.identical to that produced
under OS except for the entry point of the first main program. The
entry point of this main program is the name of the source file. If
the name of a source file is the same as the name of a subroutine in-
cluded in the source file, a subroutine call generates a catastrophic
branch to the beginning of the main program and the subroutine can
never be executed.
In summary, don't make subroutine names do double duty as file
names.
3) PL360 is Available
The PL360 programming language is available for use under the CMS
time sharing system. PL360 includes many facilities of symbolic as-
sembly languages but has an ALGOL-like syntax.
The command format is:
PL360 filename (option 1 ... option n)
Options:
PRINT prints the listing file on the off line printer and
deletes it;
NODECK suppresses the TEXT file;
NOLIST suppresses the listing file.
The manual, "PL360, A Programming Language for the IBM 360" by Michael
A. Malcolm is available in the Computer Center Library, In-162.
This CP/CMS note corrects an erroneous item in the last Newsletter.
FORTRAN H CAN HELP SPEED UP LARGE PROGRAMS
We are told that many users with large problems have never heard of
the FORTRAN H compiler which is available under.OS/MVT. To quote from
Section 5.1.1 of the User's Manual: "FORTRAN H (is) an IBM processor
which produces highly optimized code which may be desirable for special
production programs, such as large thesis projects." The cataloged pro-
cedures for using FORTRAN H are summarized on page 5-9 of the Manual. In
general, use of FORTRAN H instead of G will increase compiling time but
decrease execution time. Some specimen runs have shown a 3-5 times im-
provement in execution time over FORTRAN G. Other questions about FORTRAN
H can be answered by the Programming Consultant, In-146.

STATISTICAL SERVICES
In the last Newsletter we announced the availability of TN 0211-22,
Statistical Resources of the W. R. Church Computer Center by G. P. Lear-
month. This publication describes the pre-compiled programs available to
users in the library, STATLI Other Technical Notes that should be help-
ful to users with stats c roblems are TN 0211-19, Directions for
Using SPSS (Statistical Package for the Social Sciences) and TN 0211-20,
SNAP/IEDA Computing Package User's Manual. Copies of these notes are
available in In-147. We would like our users to help themselves whenever
possible by reading the documentation provided before asking for individ-
ual help.
Additionally, p-rofess?rs..who plan to use statistical routines in
their classes during Quarter IV are encouraged to contact Mr. Learmonth
(In-102, X2672). He is ready, willing and able to describe the available
routines to any class and to give directions for using them. A short talk
of this kind given to a whole class could save us many hours of repetitious
consulting time with individual students.
FORMAC TECHNICAL NOTE - LEAVE THE ALGEBRA TO THE 360
FORMAC (FORmula Manipulation Computer) is a package providing a tool
for performing symbolic manipulation of mathematical expressions. FORTRAN-
FORMAC, which has recently been installed at NPS, is a superset of FORTRAN
and provides the usual features of that language as well as the abilities
of FORMAC to differentiate, evaluate, group expressions, etc. Technical
Note 0211-23, User's Guide for FORTRAN-FORMAC at NPS by Sharon Raney is
available (in In-147) to assist potential users. A new cataloged procedure
for fast turnaround of FORTRAN-FORMAC jobs is described in Section 7.5.6
of the User's Manual (Update 20).
REVISION OF TECHNICAL NOTE ON TAPE CONVERSION
A new edition of TN 0211-08, Procedures for Converting 7-Track Mag-
netic Tapes to 9-track Magnetic Tape has recently been issued. This note
by Sharon D. Raney is useful primarily to users who want to work with 7-
track tapes from outside sources (such as Fleet Numerical Weather Central
the EE Computer Lab) on the System 360. However, it also contains much
useful information for all users of magnetic tapes at the Center. Copies
are available at the Information Services Office, In-147..

Accounting Data
The user identification number issued when a user first registers
with the Computer Center is valid for as long as he is assigned to the
School. If a change takes place in a user's status, i.e., going from
student to staff, or there is a change in his organization, mailing or
section code,'the Information Services Office (In-147) should be notified
as soon as possible.
Project Numbers
With the close of Quarter III, on 23 March, class project numbers
1400 through 1458 became invalid. New numbers will be issued by the In-
formation Services Office (In-147, X2731) for Quarter IV classes. Current
individual project numbers are valid until 30 June 73.
User's Manual Update
All registered holders of the User's Manual should have received
