[NTG-context] Re: Why didn't I get the correct ordinal number, after defining an environment via command "installcounterassociation".

Thank you so much. I think I understand its usage. Also, regarding the "ifargument" command you mentioned, is it counting from 0 and then checking the arguments one by one? Because I only learned "iffirstargument", "ifsecondargument" from the wiki. Perhaps we should update the section on the wiki on defining optional parameters.
