So far I have this:

<cfloop collection="#Form#" item="ThisField">
  <cfif len(form[ThisField]) LT 1>
    <cfoutput>
        #ThisField# is blank<br>
    </cfoutput>
  <cfelse>
    <cfoutput>
      #ThisField# is populated<br>
    </cfoutput>
  </cfif>
</cfloop>

Which outputs the field name and if populated or blank.

How can I set the VALUE of each blank field to "NUll" or "EMPTY" or anything?

Should I be using a list?

This should do it:

<CFLOOP LIST="#form.fieldnames#" Index="field">
<CFIF len(evaluate('form.'&field)) eq 0>
  <CFSET 'form.#field#' = "NULL">
  #field# value is NULL<BR>
<CFELSE>
  #field# value is #evaluate(field)#
</CFIF>
</CFLOOP>

#field# value is NULL
#field# value is #evaluate(field)#

This is the output I get...Am I missing something?
