Digit validation check control in instruction execution

A computer system for facilitating processing within a computing environment, the computer system comprising:

• a memory;
• and
• a processor coupled to the memory, wherein the computer system is configured to perform a method comprising:
• obtaining an instruction to perform one or more operations using at least one input value, the instruction being a single architected instruction, and the instruction comprising a no-validation indicator for controlling whether digit validation check control is enabled for execution of the instruction;
• and
• executing the instruction, the executing comprising:
• 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, wherein based on the no-validation indicator being set to a defined value, digit validation check control is enabled and the processing comprises 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.
