>Replacementstring can be any case (it is "STRT(" in the example code). Searchstring can be anything, even a subset of replacementstring.

Here is what I meant :

lcStr = 'foxpro is nice'
lcSearchStr = 'foxpro'
lcReplacement = 'Visual foxpro'
_cliptext = lcStr
 
DO WHILE OCCURS(lcSearchStr, LOWER(_CLIPTEXT))>0 AND !CHRSAW()
   _CLIPTEXT=STUFF( _CLIPTEXT, AT(lcSearchStr, LOWER(_CLIPTEXT) ), ;
      LEN( lcSearchStr ), lcReplacement )
   ? _cliptext   
ENDDO
