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.
