Hi Seb,

I had a similar issue with second order low pass filters and what you
actually want is object orientation. And since we don't have support
for this in Jal, we have to emulate this.The way to do this in C is to
create a structure with all relevant info in it. But since we don't
have stuctures eiher, we need to add each relevant var as a calling
parameter.
This is a good way in case you call the library only once or twice for
each instance, the number of parameters is not too large and there are
not many internal call within the library which require many paramters
to pass (although you could use 'internal' global vars to cope with
this).
A pre-defined number of instances (should be a compile time constant)
is an alternative if the library is called for the same instance from
many points in your code.

In short: if you only have two bits that relate to the object, make
them calling parameters.
