errors in ex.err

I've been getting less than useful error msgs lately, from an app that has run 
for years fairly flawlessly (except for the strange errors i reported and got 
laughed at here, and so i restart the app when i detect them), but this one i 
don't see how i can detect in advance:

<from ex.err>
================
u:\newsgetter\Eu webgetter tcp4u\Getabcnews4.exw:478
slice lower index is less than 1 (-4) 

u:\newsgetter\Eu webgetter tcp4u\Getabcnews4.exw:478	        if length(href) 
and not equal(href,"") and

 href = {47'/'}

===========================
</from>

The entire if-then code is:

if length(href) and not equal(href,"") and
           (not match("/REUTERS",upper(href))) and
           (not match("/AP",upper(href))) and
           (
           (not match(".HTML",upper(href[length(href)-5..length(href)]))) and
           (not match(".HTM", upper(href[length(href)-4..length(href)])))
           )
          then href = ""
        end if

As you can see, i FIRST test to see if there is anything at all in href, and
that
is where Eu is reporting i made a mistake. Naturally, i am now testing to see 
if (length(href) > 5) .
