inquire in windows - special folder / file status 12 61 (6/28/2009 3:27:13 PM) comp.lang.fortran I came across an interesting situation. I check the existence of a file in my program before executing some code. Here's the snippet of the code that does the check: ! ! do adjustl() for all elements of strarr... Ragu

EOF during Internal List-Directed Read 10 42 (5/6/2009 2:32:09 PM) comp.lang.fortran I am using a parsing (lexing) module to split the input into different string tokens (CSV). Then I use internal read to get the real, integer or character value of a token. When the string token is blank or em... Ragu

How to return a variable length substring from a function ? 54 64 (1/27/2009 9:33:56 PM) comp.lang.fortran Hello, I have a function that returns a variable length character substring. Depending on the input, the output is either 1 to 3 characters long. How can I return a character(len = 1) or character (len = 2) or... Ragu

Returning a dynamic character array based on input length 19 43 (9/10/2008 8:20:43 PM) comp.lang.fortran I have a simple question regarding allocating a character array that can represent a line in an input file. I am writing a small function that can read a line from an input file, strip the Fortran 90 style comm... Ragu

Interpreting read statement in FORTRAN IV code 16 37 (8/19/2007 10:01:09 PM) comp.lang.fortran I am trying to understand a code that had its origin since FORTRAN IV days (1970's I guess). A particular line tries to read values from a binary tape. In loop 100, "L" values are skipped. Note that there are ... ssragunath

Source code beautifier for f90 and f77 6 63 (9/11/2008 5:15:25 PM) comp.lang.fortran Hi! I have loads of legacy code in f77 and written lots of f90 code myself. To make the code easier to read and to give all sources a uniform look, I would like to pass my code through a program that tidies up... arjan.van.dijk (248)

how to declare doubles in f95 40 55 (1/29/2009 1:18:44 AM) comp.lang.fortran I have this fortran program that's kind of a hash-mash of 77 and 90/95. The original author used real*8 to declare his floats (I'm guessing the intent was for them to be double precision floats). Gfortran, us... einazaki668 (40)

Can an executable ask itself how and when it was compiled? 7 32 (3/4/2009 7:27:30 PM) comp.lang.fortran Sometimes my results differ when I compile my program with different switches, or on a different machine or with a different compiler. Therefore I would like to write to stdout how the executable doing a partic... arjan.van.dijk (248)
