FREE_LUN supposed to work in a loop? [message #84431] Sat, 01 June 2013 21:40

Hi there,

I'm getting "OPENR: All available logical units are currently in use" when running something like this:

for i = 0, n_elements(texts)-1 do begin
openw, lun, control_file, /get_lun
printf, lun, 'some text'
free_lun, lun
run_this_procedure ;this is a *.pro that uses the control_file just created above
endfor

If I do "help, /files" I see that all units have been closed but are still reserved. Why?! Any suggestion?

Thanks!
