Sorry about that. The TCC Operator's Manual was slightly stale in this area. I made the necessary corrections, to wit:
$ dopterr
does not accept any parameters any more. As you unfortunately had to find out the hard way, it always writes data to:
  tpterr:pterr_yyyymmdd.dat
(and tpterr is a logical name, i.e. shortcut, for [tcc.pterr])
What I did not mention in the manual, but will say here, is that if you run it again, the data goes into a new version of the same file. Also, if you edit a file, the changes are saved to a new version. In other words, standard VMS file handling.
Thank you for saving and implementing the new model!
