Thank you for your email. You are correct in your assertion. I have felt that

Thanks for the email - and sorry to be so slow getting back to you. Our current
work in this area relates to instructions as a generic class in the reference

The links between individual instructions can modelled in a number of ways:
1. The start condition for one instruction
will want to use this for all sorts of reasons, one clear
example is when an electrolyte sample has haemolysed - and they cannot
give a potassium reading (they do not want to omit it!)
