On the Compaq Fortran language, see the Compaq Fortran Language Reference Manual.Ī.2.2 Language Features Provided Only by Compaq Fortran 77 for Compaq Tru64 UNIX SystemsĬompaq Fortran conforms to the Fortran 95/90 standard, which is a Symbolic parameter definitions for use with run-time (IOSTAT) error For example, a Compaqįortran 77 procedure and a Compaq Fortran procedure can perform I/O to Routines and a common run-time environment.
The ability to call between Compaq Fortran 77 and Compaq Fortran. A nearly identical set of command-line options and their associated. OPTIONS statement to override or set compiler command-line options. INCLUDE statement forms using /LIST and /NOLIST (requires compiling. (see the Compaq Fortran Language Reference Manual), including: Compaq Fortran 77 compilation control statements and directives. In addition to language extensions, Compaq Fortran also supports the 
Additional language features, including the DEFINE FILE, ENCODE,. USEROPEN routines for user-defined open routines. The tab source form (resembles fixed-source form). Built-in functions used in argument lists, such as %VAL and %LOC. The POINTER statement and its associated data type (CRAY pointers). IEEE floating-point data type in memory. Size specifiers for data declaration statements, such as INTEGER*4,. Certain data types, including 8-byte INTEGER and LOGICAL variablesĪnd 16-byte REAL variables (available on Alpha systems). I/O statement specifiers, such as the INQUIRE statement specifiersĬARRIAGECONTROL, CONVERT, ORGANIZATION, and RECORDTYPE. I/O statements, including PRINT, ACCEPT, TYPE, DELETE, and UNLOCK. Record structures (STRUCTURE and RECORD statements). To simplify porting applications from Compaq Fortran 77 toĬompaq Fortran on Tru64 UNIX systems, Compaq Fortran supports theįollowing Compaq Fortran 77 extensions that are not part of the Fortran Language features detected during compilation differently by Compaqįortran than Compaq Fortran 77 for Compaq Tru64 UNIX SystemsĪ.2.1 Major Language Features for Compatibility with Compaq Fortran 77 for Compaq Tru64 UNIX Systems.
