procedure comments are not allowed

[essentialexch]

ALGOL-60 provides for extended comments in procedure declarations, e.g.:

REAL PROCEDURE A (Z) is the array :(L) is the lower bound :(U) is the upper bound :()
    VALUE L, U;
    INTEGER L, U;
    ARRAY Z[0];
    FORWARD;

You do not allow this.

Can refer me to the clause in the original stds spec:

See 3.2.1 for definition. See 5.4.2 for an example.
