problem with text file output

[Cammer, Michael]

I am having a problem and don't know if I'm overlooking something obvious or if there is a bug in the daily build (updated a few minutes ago).

The following code opens a new text file in the correct location and the Debug window shows correctly
outputFile (g)    *             "G:\VickieTest\file_one-2_results.txt"
(Yes, I know the getTitle is redundant, but I cut and pasted from somewhere else.)

      currentpath = openPath + fileList[dir];
      currentList = getFileList(currentpath);
      //Array.show(currentList);
      filecount = 0;
      while ( !(endsWith(currentList[filecount], ".tif")) ) {
        filecount++;
      }
      open(currentpath + currentList[filecount]);
      title = getTitle();
      print(title);
      newTitle = replace(title, ".tif", "_results.txt");
      outputFile = openPath + newTitle;
      File.open(outputFile);

However, the file remains empty even though there are a series of print commands such as these:

      print(outputFile, title);
      print(outputFile, outputString);

The macro then crashes with the command

      File.close(outputFIle);

The file cannot be deleted in Windows because it is still open.

Any help appreciated.

Thanks.

Hi Michael,

you have to use the *result* of File.open as the first argument of the print function (not the path to the file).
See this example macro
