Re: analog_expression and analog_operator

Hi Laurent,
No I don't believe this is the case, the BNF is not expressed correctly 
in 2.2 for this situation. Ideally you can use an analog opertor 
anywhere within an analog block as long as it is evaluated at each 
iteration of a time point (so you can't use them in conditional code). 
In 2.2 the BNF should include a rule for:
| analog_expression binary_operator analog_expression

In the latest draft that is being worked on, the BNF has been corrected 
to include this rule. In fact the BNF in the latest draft is greatly 
improved and addresses lots of ambiguities such as this.

Cheers...
Dave
