Do you mean you want to have the full text of the file as a string in
your structure?
If so, it's not so bad:
nlines = file_lines(filename)
lines = strarr(nlines)
openr, lun, filename, /get_lun
readf, lun, lines
free_lun, lun
cr = string([10B]) ; string([13B, 10B]) on Windows
text = strjoin(lines, cr)
If you have my library, it's just:
text = mg_strmerge(mg_file(filename, /readf))
Then:
btstruc = {mm: momentmm,$
ros: btstruc.ros, $
readme: text}
