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.
