c Asnag1 assigns logical unit lu to a direct access disk file
c with mode "mode" and record length "len". See dasign for
c details. The n th argument is used as the model name. If there
c is no n th argument and ib is non-blank, it is taken to be the
c model name. If ib is blank, the user is prompted for the
c model name using the character string in variable ia as the
c prompt. Programmed on 8 October 1980 by R. Buland.
