By the way, I have a template class which is very handy for doing much
of this type of stuff.
For example,
template = obj_new('MGffTemplate', 'template.tt')
template->process, { this_gmag: strtrim(12.399, 2) }, 'template.html'
obj_destroy, template
In the template.tt, would be:
<dt>g Mag:</dt><dd>[% this_gmag %]</dd>
In your small example above, it's not hard to use PRINTF, but if you are
generating an entire HTML file, it's pretty painful. The template syntax
also allows FOR loops, IF statements, etc.
