Is is a chr(0) by any chance? If you step through each character in the field, determine what it is and strip it out. You can do something similar to:

SCAN
   lcstring=ALLTRIM(mytable.myfield)
   ? lcstring
   istop=LEN(lcstring)
   FOR i = 1 TO istop
      ? ASC(SUBSTR(lcstring,i,1))  && determine what the chars are
      IF ASC(SUBSTR(lcstring,i,1))=0  && if it is chr(0), strip it out
      	REPLACE mytable.myfield WITH LEFT(lcstring,i-1)
      ENDIF
   ENDFOR
   ? mytable.myfield
ENDSCAN

>I am useing an EditBox to enter a drawing title into my table. After the title is input there are extra chractors in the string, two heavey vertical bars. This causes a problem when I need to include this string in SPT. How can I strip these charactors?
