Welcome to the club :-) (although I am not a member of it anymore).

The ARM is written in "computer science legalese," one of the most obscure form of communication after cryptography... :-)  

Seriously, the ARM is not a tutorial, but a standard document and this kind of prose is a consequence of that.  I know that the ARM is not an easy reading when you are a beginner, but you'll get used to it and then it will be a fundamental and precious reference for you (personal experience).

What the excerpt that you posted say is that an actual_parameter_part is a sequence of one or more parameter_association separated by comma and included between parenthesis.  Every parameter_association can be both a value (called explicit_actual_parameter in the grammara) or a string of type "name => value" (where name is an identifier and its called formal_parameter_association_name in the grammar).

If you post your code and the error message, we can be more precise.
