Atas is a conlang about which much not is known. It was created by Patrick Dunn during or before 2004. It may or not have had influences from or a similar structure to Indonesian.
What little is known of the language's structure and grammar can be found in a handful of posts on the conlang mailing list and in the notes from Conlang Relay 10, in which Atas was used.
On the grammar of Atas
Please note: This section was not taken from Langmaker, and thus may be licensed differently than the rest of the article.
In the 10th Conlang Relay, the author of the language said this:
"Atas is SVO, with modifiers following their heads. Sentential adverbs always come before the sentence. Personal pronouns following nouns indicate possession, except for the third person suffix -ya, which can also indicate definiteness. The third person is suffixed and causes phonological weirdnesses that aren't reflected in the orthography, so you can ignore them. Some prefixes (notably piN-) have an underlying nasal, but that shouldn't cause you much problem. Reduplication of nouns indicates plurality. Reduplication of verbs can indicate intensification or reciprocity (among other things)." (found here)
