I'd be inclined to do away with the 'BigString'; there may be times you
don't know how big to make it. Here's what I use - just prototype to return
a STRING:
Replace PROCEDURE(STRING Text,STRING Find,STRING Replace,BYTE CS=FALSE)
Pos UNSIGNED,AUTO
RVal ANY ! Do not add ,AUTO
CODE
LOOP
Pos =
CHOOSE(~CS,INSTRING(UPPER(Find),UPPER(Text),1),INSTRING(Find,Text,1))
RVal = RVal & CHOOSE(~Pos,Text,Text[1 : Pos-1] & Replace)
Text = CHOOSE(~Pos,'',Text[Pos+LEN(Find) : LEN(Text)])
UNTIL ~Text
RETURN RVal
