Abstract: Digit validation check control for execution of an instruction. A process obtains an instruction to perform operation(s) using input value(s). The instruction includes a no validation indicator for controlling whether digit validation check control is enabled for execution of the instruction. The process executes the instruction, including determining, based on the no validation indicator, whether digit validation check control is enabled for execution of the instruction, and performing processing based on the determining. Based on the no validation indicator being set to a defined value, digit validation check control is enabled and the processing includes forcing a digit check error indicator output by the executing to indicate no digit check error with respect to the at least one input value.

Abstract: An instruction to perform scaling, converting and splitting operations is executed. The executing the instruction includes scaling an input value in one format to provide a scaled result. The scaled result is converted from the one format to provide a converted result in another format. The converted result is split into multiple parts, and one or more parts of the multiple parts are placed in a selected location.
