The open system call returns the file descriptor, which must be returned as a 4-byte integer to the DIGITAL Fortran 90 program (and DIGITAL Fortran 90 RTL). After control (and the file descriptor) is returned from the called function, the main DIGITAL Fortran 90 program can perform I/O to that logical unit with Fortran 90 statements Yes, code "STATUS = 'OLD'" on the OPEN statement. If the file may not. exist, then STATUS='OLD' will fail; for this case (in AIX xlf V2) you. can code "STATUS='UNKNOWN'" and compile the program with the. "-qposition=append option. This will append to a file if it exists, and create a new one otherwise. I'm guessing that you're on an AIX system Create and run a FORTRAN 95 program Understand basic program structure Start to deal with programming errors Start to understand real, integer and character variable types.

Below is some simple code that compiles with pgf90 but not with pgf77. Removing the POSITION='APPEND' clause allows it to compile cleanly. prompt> cat pgf77_test.F SUBROUTINE OPENAPP(CFILE,IU) CHARACTER ()CFILE. OPEN(IU,FILE=CFILE,STATUS='OLD',POSITION='APPEND') A Fortran 90 compiler is required to report any non-conforming code (i.e. the use of statements or variables which are illegal under the rules set out by the ANSI stand-ard). As well as reporting errors a Fortran 90 compiler is required to provide a reason for reporting the error. This should help programmers to write correct code. As mentioned, Fortran 90 has been augmented with a number of new features to take advantage of modern computing needs and developments; developments such as the System specific information such as this is provided in the language reference manual on most systems. The following keywords are specified in the Fortran 90 language standard: FILE=filename. 'REWIND' or 'APPEND' which are interpreted as positioning the file at the position it was previously accessed, positioning the file at the start Fortran 90 and ORACLE Insert. 3.
