Well, suppose you obtained your file list like this:

filelist = File_Search('*.pro')

Then, you could print the list out, with double quotes around
each file name, like this:

OpenW, lun, 'output.txt', /Get_Lun
FOR j=0,N_Elements(filelist)-1 DO BEGIN
PrintF, lun, '"' + filelist[j] + '"'
ENDFOR
Free_Lun, lun

Suppose you wanted to add the index number of the file
to each filename, you could do something like this:

OpenW, lun, 'output.txt', /Get_Lun
FOR j=0,N_Elements(filelist)-1 DO BEGIN
PrintF, lun, '"' + filelist[j] + '"' + ' ' + $
String(j, Format='(I2.2)')
ENDFOR
Free_Lun, lun

You could also format your string with a FORMAT statement
to the PRINTF command, similar to what I used with the
STRING command, above. There is almost infinite flexibility
in how this is done.

Cheers,

David
