Null value in Collection substring

[Leslie Clark <lclark@US.IBM.COM>]

Have you tried < something? Ascii null is 00, space is 20, then ! is 21,
then the numbers,
then the uppercase letters, then the lowercase letters. So <! ought to
catch both those
that show up as null and those that show up as blank, and you don't have to
deal
with feeding a blank or a null to the collection editor.  (This is why I
carry around my
old S/370 Reference Card!)

Now... everybody go home! Get a life!

Cordially,

I'm trying to create a collection for resources that have no sysContact or
sysLocation information defined.  I'm sure theres a simple answer to this,
but I've tried everything and I am stumped.  How do you define a null value
for the substring field entry after selecting the sysContact and
sysLocation attributes?
