I'm glad it is working out for you.

OK, no problem.  I'll add them to the table of routines to convert.  I 
notice in PGanswermacros.pl that in addition to setting the filters, 
they also set a type flag.  Do you want that to be included in the 
conversion?  That is, should

	strict_str_cmp("foobar")

produce

	str_cmp("foobar",filters=>'trim_whitespace')
or
	str_cmp("foobar",filters=>'trim_whitespace', type=>'strict_str_cmp')

I think it should be the former, but I don't know how the type flag 
might be used later on, if at all.  I suspect it is just informational 
and can be ignored.

Also, do you prefer

	str_cmp("foobar",filters=>'trim_whitespace')

or just

	str_cmp("foobar",'trim_whitespace')

as the result?

right

That one should already be handled by the version you have.  It is 
converted to

	ANS(num_cmp($ans, strings=>['N']));

which is what you want, right?

I'll send an updated version when I know how to handle the 'type' flag 
above.
