Remove trailing spaces

[kai_larsen]

Hi!

I need to tell my fortran program which directory to find all the files it will work with. To accomplish this, I use a text parameter through CALL GETARG().

I then

filename = workingdirectory // 'filename.dat'

OPEN(50,FILE=filename,FORM='FORMATTED')

Unfortunately, this leads to the following content in filename:

c:directory1 est svd2b.dat

I need a way to remove all the spaces. Any advice is greatly appreciated!

Thanks!

Use TRIM(workingdirectory)//trim(filename)

Thanks! That helps a lot. Unfortunately, that seems to remove spaces from anywhere in the string (since I'm dealing with directory names, it removes some crucial spaces). Is there any way to remove only trailing spaces?

If so, something else is wrong.

TRIM( ) only removes trailing blanks. Standard Fortran since "forever".

It is best you read the manual, or type "trim fortran" into Google .

Thanks David!

You are right, of course, and I did actually google the problem before asking. I just realized that TRIM was not my problem.

As I mentioned above, I use GETARG() to get the directory name as a command line parameter. Unfortunately, it turns out that when the directory name contains spaces, these are treated as different parameters. Arg(h)...

I guess my question is whether there is a way to cap a string so that GETARG understands that it is one string rather than two (or 3,4,5,6)? I've tried Google with no luck, and my guesses of "c:dir 1" and 'c:dir 1' don't work.

Use double quotes ( application.exe "here is the argument")and it will work fine.

Just to prove it, here is a simple Fortran console .EXE which I copied to the root directory c: and then ran from the Start..Run...command line as

c:getargument "here is an argument"

which gave the console output shown in the screenshot.

This is the standard behavior for Windows (and Linux and UNIX) - spaces are considered separators in command line arguments. As Anthony says, enclosing the string in quotes preserves the spaces.

If you don't want to do this, you can add a space between each argument you retrieve with GETARG.
