I always pass a fix length as a parameter between Modules. It would be nice when dealing with a field that has the potential to be rather large to define it as a variable length. The method that Scott and Brad discuss is this the best way to do this?
Depends. Why do you want it to be variable length? You say that it would be "nice", but you don't say _why_ it would be nice.
To put it another way, what are the goals and requirements of the module that you're writing? Is performance a high priority? Is ease of use more important than performance? Is versatility (ability to pass any size/type variables) more important than ease of use?
