No spaces in downloaded txt file

Hi Members:

I have a question and I expect you could help me.

I have to download a txt file to be exported to another system. This file must have a length of 200 characters in each line, but the text in the many times is only 180 or 150. In these cases, the rest of line must be completed with spaces. But when the file is downloaded there is no spaces in txt file.

I have used TRUNC_TRAILING_BLANKS in GUI_DOWNLOAD, but it does not work. I am working with release 4.6C

Do you know how I can solve this?

Thanks in advance for your help.
