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.

The template is an IDL structure. You can save it to disk with SAVE and
restore it with RESTORE.
Here's how I would do it:
function read_myfile, file
common myblock, template
if n_elements(template) eq 0 then begin
template_file = <specify your template file name here>
case file_test(template_file, /READ) of
0: begin
template = ascii_template(file)
save, FILENAME=template_file
end
1: restore, FILENAME=template_file
endif
return, read_ascii(file, TEMPLATE=template)
end
