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
            1: restore, FILENAME=template_file
    return, read_ascii(file, TEMPLATE=template)
