For example, I have a write command to save an array with 6 fields in a text file like this:
Now I want to read and save the 6 values of the last line of my text file in another array with 6 fields like:
This could be the content of the last line in my file:
The aim is to save the last line in existing format.
But after doing this I always get values 0.000000E+00
. How can I read and save the last line of my 'W:Partikeltemperaturfeld.txt' file in array TEST(1:6)
?
If you do
the loop will exit when there was some problem (end of file or an error condition) reading the array in the input list. The value of the variable being read is than undefined. You cannot use it. It can contain anything.
BTW your code is not Fortran 77 conforming (it is Fortran 90 or later) so I will not try to make my suggestion 100% Fortran 77 either. You can do
where TEST
and TMP
are arrays of size 6
X-force keygen autocad lt 2014. I have a file with 1000s of numbers like:
Depending on an input parameter 'n', I want to read 'm' numbers from this file from line numbers 'n' to 'n+m-1'.
Any ideas how can I do this in Fortran?
I don't know if you have tried it yourself, but here is an minimal example:say, your input file looks like this:
use this code (after reading it)
This skips first n line, and reads p lines after that.Hope that helps
Blue iris download crack. The response I get from Blue Iris is a key for the old version 3 of blue. A keygen is made available by crack groups free to download. I found a free program online that so far is.
may be,
is what you are looking for. this is untasted, but may give you a go.
edit: direct access is better for this type of job:Just realised, though this is the easiest one, not the preferred one.You can open the file in direct access mode and complete your job as:
Purpose: Create a program that takes two separate files, opens and reads them, assigns their contents to arrays, do some math with those arrays, create a new array with product numbers, print to a new file. Simple enough right?
My input files have comment characters at the beginning. One trouble is, they are '#' which are comment characters for most plotting programs, but not FORTRAN. What is a simple way to tell the computer not to look at these characters? Since I have no previous FORTRAN experience, I am plowing through this with two test files. Here is what I have so far:
PS. Please do not overwhelm me with a bunch of code monkey gobblety gook. I am a total programming novice. I do not understand all the lingo, that is why I came here instead of searching for help in existing websites. Thanks.
Write a subroutine that puts this logic into one spot for you so you can call it for both files. You'll need to read each line as a string and add an IF test to check whether a given line starts with a '#' or not. If the line starts with a '#', just read the next line. If not, convert the string to a value and add it to the array of values you're returning.
If you mean that the comments are only at the beginning of the file, it is fairly simple -- no need to count the comment lines or rewind file -- you can read the lines into a string and test whether they are a comment. Then you will eventually encounter a non-comment line. Problem: it will have been read into a string and thus not available for a regular read .. solution .. use 'backspace' to unread one record so that you can now use normal file reads to read the rest of the file. A slightly more complicated solution would be necessary if comment lines were interspersed throughout the file -- as already stated, read the lines into a string, then read from the string.
Here is a worked example .. I have assumed that the '#' is in the first column and various other simplifying assumptions. Some recommendations: put your subroutines and functions into a module and 'use' that module -- this will allow the compiler to check the interfaces. As you are developing your programs, use as many code checking and warning options as possible -- especially subscript bounds checking -- it will save time in the end.
P.S. It is officially 'Fortran' since Fortran 90 -- it was 'FORTRAN' for FORTRAN 77 and earlier.
And some test data to show how flexible the input data can be:
I'm not real familiar with anything beyond FORTRAN 77 but here are a few pointers (and a working version of what you posted in your answer). First the working code (I added line numbers):
The differences are:
Instead of using a function, you could define this your myfile routine as a subroutine instead. In this case you would definitely need to pass in the array you want filled as a parameter. You wouldn't need line 10 and instead of assigning the return value to a variable in the main program you would 'call' the routine. i.e. line 14 would look like this:
EDIT:I posted this and then realized I forgot to answer the original questions. I did so and then for some reason couldn't connect to SO to upload the edits. So here they are finally.
That gets your routine compiling. To actually deal with the comment lines, you have several options (at least these are the ones that come to mind initially). These are in order from simplest/most brittle to more robust/general:
Which method you choose (and other people may have other suggestions) depends on your particular application. Good luck.
