This probably means that your variable XX is an array (possibly with one element). Try

filename = 'maks'+strcompress(xx[0])+'.txt'
File1 = filepath(filename,subdirectory = ['Final'])
openw,lun,File1,/get_lun

As a side note:

IDL> print, filepath('somefile',subdirectory = ['Final'])
/usr/local/exelis/idl82/Final/somefile

Are you sure you really want to write to the default IDL root directory? If not, you can do something like this:

IDL> root_dir = '/my/data/directory/'
IDL> print, filepath('somefile',subdirectory = ['Final'], root_dir=root_dir)
/my/data/directory/Final/somefile
