Thanks group for the links to the source. These have passed thru many copies, and somehow have embedded control characters and such, but I am successful so far at the cleanup: I pull the source into a fortran knowledgeable editor, I am using "blocks" When the editor stops in the file, I drop into jedit, delete whatever is there, the invisible text and save; restart "blocks" and it parses further I should have this to compile in a few days. It outputs to the Tek terminal, for those guys working on that. Randy
