Today is the first time I have seen a sentence end with とあります。
Is it same as であります or があります?
The sentense is:
「横書きの書き方にはコンマを用いるとあります。」
This とあります really surprised me because I haven't seen it in any grammar books.☝
When the need to be completely objective in communicating information on data or materials overrides the importance of specifying the particular nature of the rendering *「~と述べられてあります」 「~と記されてあります」「~書いてあります」etc.* I suppose とあります is useful.

A unifying standard of 『。』 and 『、』 for both 横書き and 縦書き was not taken up until the late 1950's I believe but there were so many political considerations with American influence at the time, it would be very interesting to be able to put the Basic Sentence Rules and Punctuation Rules all in a bit more context.
