<ot> Well FORTRAN would have to have *something* going for it :-) I vaguely recall in a previous incarnation tarting up a vanilla ratfor "compiler" with switch statements and macros and all sorts of goodies so that life was less unbearable :-) [this was *before* f77] </ot> Suggestions: (1) Upgrade to 2.5 as soon as it goes final -- struct's performance has been improved. (2) Consider the possibility of not unpacking all three variables if you don't need to -- for example if you are ignoring everything until you hit a record that starts with 'DIMENS ', you don't need to unpack anything, just do: if buff[:8] == 'DIMENS ': How big are your files, anyway?
