A conditional instruction end facility is provided that allows completion of an instruction to be delayed. In executing the machine instruction, an operand is obtained, and a determination is made as to whether the operand has a predetermined relationship with respect to a value. Based on determining that the operand does not have the predetermined relationship with respect to the value, the obtaining and the determining are repeated. Based on determining that the operand has the predetermined relationship with respect to the value, execution of the instruction is completed. The obtaining the operand, the determining whether the operand has the predetermined relationship, the based on determining that the operand does not have the predetermined relationship with respect to the value, repeating the obtaining and the determining, and the based on determining that the operand has the predetermined relationship with respect to the value, completing execution of the instruction are performed as part of a single instruction having one operation code. |
