> Another question just came up. In order to control my processing process with a lot of files I'd like to create two lists (txt.'s). One list contains the properly processed (ok_list) and one list the corrupt files(error_list). Based on an exitcode from my processor I'd like to write the name of the currently processed file into the correct list.

Read the manual for the OPENW command and find the APPEND keyword?
