str = StrReplace(sFull,sOld,sNew,bAll,bIgnoreCase)
•bAll : when this parameter is true, all occurrences of sOld will be replaced, otherwise only the first occurrence will be replaced.
•bIgnoreCase : when this parameter is true the search for occurrences of sOld is case insensitive. So in that case a value 'for sOld of 'nasa' would also find occurrences of 'NASA' and 'Nasa'.
