Software Product Description
PRODUCT NAME: VAX-11 FORTRAN, Version 2.0
(Formerly VAX-11 FORTRAN IV-PLUS)

DESCRIPTION:
VAX-11 FORTRAN is an implementation of full language FORTRAN-77 conforming to American National
Standard FORTRAN, ANSI X3.9-1978. It includes
optional support for programs conforming to the previous standard, ANSI X3.9-1966. The shareable, reentrant compiler operates under the VAX/VMS operating system to take advantage of the VAX-11 floating
point and character string instruction set and the
VAX/VMS virtual memory operating system.
VAX-11 FORTRAN includes the following extensions
to the ANSI standard:
• Language elements for keyed and sequential
access to VAX-11 RMS multikey ISAM files
• A set of data types beyond those specified for full
language FORTRAN-77:
- LOGICAL *1, BYTE
- LOGICAL*2
- INTEGER*2
- COMPLEX*16, DOUBLE COMPLEX
• Explicit specification of storage allocation units for
data types (e.g., REAL *8, INTEGER*4)
• Data initialization in type declaration statements
• DO WHILE, ENDDO statements
• Bit manipulation functions
• Hexadecimal and octal constants and Z and 0 format edit descriptors applicable to all data types
• ENCODE, DECODE statements
• ACCEPT, TYPE input/output statements
• DEFINE FILE statement
• USEROPEN subroutine invocation at file OPEN
time
• INCLUDE statement
• 31-character identifiers that can include dollar sign
($) and underline(_)
• Comments allowed at end of each source line
• Debug statements in source
Additional features:
• Support for calls to VAX/VMS system service
procedures
