Wow, I had no clue about that difference either.
Good info, thanks.

Is there documentation explaining about the use of parenthesis? I was
unaware that there is a difference when you do not specify the parenthesis.

When you don't specify the parentheses, the compiler uses the normal historical rules for Factor 2 of a fixed-form statement which require an exact match.

Here's where it says that a list of keys can have expressions that don't have to match the file's key exactly. But I see that it doesn't say that a single field name must match the file's key.


If the file is keyed by multiple fields, wouldn't either example below
return the first record that matches the key specified? (at least that is
what is specified in the manuals I have read.)


Yes. The only difference between coding a field with and without
parentheses is that the compiler's rules are relaxed when it is a
parenthesized list. The value used actually used as the search argument
in the keyed operation would be the same.
