Software Product Description
PRODUCT NAME: PDP-11 FORTRAN IV-PLUS, Version 2.5
DESCRIPTION:
FORTRAN IV-PLUS is an extended FORTRAN implementation based on American National Standard
(ANSI) FORTRAN, X3.9-1966. It operates under the
RSX-11M, RSX-11D, and lAS operating systems. The
PDP-11 FORTRAN IV language includes the following
extensions to the ANSI Standard:
• General expressions allowed in all meaningful contexts
• Mixed-mode arithmetic
• BYTE data type for character manipulation
• ENCODE, DECODE statements
• PRINT, TYPE, ACCEPT input/output statements
• Direct-access unformatted input/output, DEFINE
FI LE statement
• Comments allowed at end of each source line
• PROGRAM statement
• OPEN and CLOSE file access control statements
• List-directed input/output
FORTRAN IV-PLUS provides the following additional
capabi Iities:
• INTEGER*4 (32-bit) data type
• ENTRY statement
• INCLUDE statement
• PARAM ETER statement
• Generalized DO loops
• Lower, as well as upper, bounds specification in
array declarators
• Generic function selection based on argument data
type for FORTRAN defined functions
• Direct access formatted input/output
The FORTRAN IV-PLUS compiler produces direct
PDP-11 machine code optimized for execution time
efficiency on a PDP-11 with a floating point processor. FORTRAN IV-PLUS compiler optimizations include:
• Optimizations of arithmetic and logical IF statements
• Common subexpression elimination
• Removal of invariant expressions from DO loops
• Allocation of processor registers across DO loops

itself use the FPP, and can thus
processors with the EIS instruction set.

Object Time System
The FORTRAN IV-PLUS Object Time System (OTS) is
a set of object modules selectively linked with compiler-produced object modules by the operating system's task builder to produce a task (program) ready
for execution. The OTS is reentrant and part or all of
the OTS can be made into a shared library for concurrent use by multiple tasks.

MINIMUM HARDWARE REQUIRED:
Any valid RSX-11 M, RSX-11 D or lAS operating system configuration which includes a:
Central processor with floating point processor
One of the following:
• PDP-11/34 with FP11-AU
• PDP-11/45, 11/55, or 11/70 with FP11-B or FP11-C
• PDP-11/60 (includes floating point processor)
that meets the following main memory and auxiliary
storage requirements.

Main Memory: - The FORTRAN IV-PLUS compiler
requires a minimum task partition area of:
• RSX-11 M operating system: 36K bytes
• RSX-11 D operating system: 34K bytes
• lAS operating system: 34K bytes
The compiler under RSX-11 D and lAS requires the
standard operating system shared library SYSRES.
Storage for SYSRES is in addition to the 34K bytes
for FORTRAN IV-PLUS. The compiler can be operated with reduced performance in 32K bytes of memory. The compiler under RSX-11M requires no additional resident library. Improved compiler performance is obtained by increasing the memory
requirement to 38K bytes for RSX-11 D and lAS and
40K bytes for RSX-11 M.

Auxiliary Storage: - FORTRAN IV-PLUS requires up
to 300 contiguous disk blocks for the compiler task.
An additional 150 to 250 disk blocks are required for
the Object Time System library file and auxiliary support files, depending on installation options. The compiler may use up to 350 blocks of temporary disk file
space in compiling large programs.

Programs which do not use real, double precision, or
complex quantities can be compiled into code which
can be executed on processors with the EIS instruction set. The FORTRAN IV-PLUS compiler does not

OPTIONAL HARDWARE:
Non-FPP Environments: - The FORTRAN IV-PLUS
compiler does not itself use the FPP, and can thus
operate on processors with the EIS instruction set.
Compiled FORTRAN IV-PLUS code requires a floating
point processor for normal operation; a subset of the
FORTRAN IV-PLUS language can be used on processors without an FPP. Programs which do not use real,
double precision, or complex variables or constants
are compiled into code which can be executed on
processors with the EIS instruction set:
• 11/03, LSI-11 under RSX-11 S (with KEV11)

• 11/34
• 11/35 or 11/40 with KE11-E
• 11/45
• 11/55
• 11/70
PREREQUISITE SOFTWARE:
One of the following operating systems is required:
• RSX-11 M, Version 2 or later, or
• RSX-11D, Version 68 or later, or
• lAS, Version 1.1 or later
