Howto Create A New .mel File To Write Values Into

[buchel]

Hi!
I'm new to MEL and got a problem with my MEL script. I collected the positions of some nodes in the scene and now i want to save these values in a file. (.txt, .mel, .xml or so)
My problem is that I want the script to create a new file with the user given filename (I made a GUI for that) but I don't know a valid command for that problem. (I searched in the doc and the forum but only found "fopen" "fprint"... ) There is no problem when the file is already existing. (fopen...blablabla)

May anyone help me, please

whats wrong with fopen/fprint?
because thats the key!
you create a new file with "fopen -w bla;"; You just need to fclose the ID and its written!
Its pretty nice explained in the docs.

btw: You can check for file existence via "file -q -ex $filename;"

Okay, this was easy (sometimes i've got little problems with english language)! Thank you.
But now i get an error:

CODE
global proc filecreate (string $pathfile)    {
    string $filetemp;
    if (file -q -ex $pathfile)    {
        print "file there ";
        //$filetemp=fopen $pathfile "w";
    }else {
        print "file not there";
        $filetemp=fopen $pathfile w;
        fprint $filetemp "Hello there\n";
        fclose $filetemp;

I get this error
Invalid call to "fprint". Check number and types of arguments expected by the procedure.

But this is exactly (I think) the example of the documentation.
What went wrong?

you do understand how string quoting wrks and that maya uses / as folder separator prefeerebly instead of \ wich must be duplicated \ to escape the quotes

problem solved:
fprint needs an int as filehandle.
My filehandle $filetemp was a string as you can see. I changed it into int and everything works fine.
Thanks for your replies.
