Re: template for READ_ASCII

Mark,
Thanks. Only change I had to make was adding an "endcase"  before the
"endif"  ... without it I got the "end of file before end or program" error.

It works great. I just didn't know how to save a structure. Now I do.
This is an incredible group --- answers to your problems while you wait.
