Unfortunately, that's not really true: the Pascal strings it supports are in some sense variable length, but are stored in a fixed-width field. The internals of the struct module rely on each field starting at a fixed offset, computable directly from the format string. I don't think variable-length fields would be a good fit for the current design of the struct module. For the OPs use-case, I'd suggest a library that sits on top of the struct module, rather than an expansion to the struct module itself. -- Mark
