Okla. Stat. tit. 12, § 12-666: Time of trial

Actions shall be triable at the first term of court, after or

during which the issues therein, by the time fixed for pleading are,

or shall have been made up. When the issues are made up, or when

the defendant has failed to plead within the time fixed, the cause

shall be placed on the trial docket, and if it be a trial case shall

stand for trial at such term ten (10) days after the issues are made

up, and shall, in case of default stand for trial forthwith. When

any demurrer shall be adjudged to be frivolous the cause shall stand

for hearing or trial in like manner as if an issue of fact had been

joined in the first instance.
