procedure call name vs.association_list ambiguity

[root]

Consider the specification,

procedure_call ::= procedure_name [ ( parameter_association_list ) ]

association_list ::= association_element { , association_element }

name ::= simple_name |

indexed_name ::= prefix ( expression { , expression } )

How do you handle (1) in PROC1(1): as association list or as expression?

Assuming PROC1 is declared to be a procedure, then the expression 1 is used as the first association element in that procedure.

Do you mean that they merge somehow? I have never heard about such
parsing technique. Normally, parser takes either name production or
association list route. It cannot end up in both expression (which is
name extension) and association element that follows it, at the same
time. Otherwise, everything is ok.
