That way you can have conditions such as "$5 > 500". So what's happening is that the line is split up before gawk gets to the point where you change FIELDWIDTHS. The new value is then used for the next record. Without knowing what your input looks like, I can't really make any useful suggestions about how to parse it. HTH Jiri <[EMAIL PROTECTED]>
