    Abstract: An instruction to perform a multiply and shift operation is executed. The executing includes multiplying a first value and a second value obtained by the instruction to obtain a product. The product is shifted in a specified direction by a user-defined selected amount to provide a result, and the result is placed in a selected location. The result is to be used in processing within the computing environment.

    Abstract: An instruction generates a value for use in processing within a computing environment. The instruction obtains a sign control associated with the instruction, and shifts an input value of the instruction in a specified direction by a selected amount to provide a result. The result is placed in a first designated location in a register, and the sign, which is based on the sign control, is placed in a second designated location of the register. The result and the sign provide a signed value to be used in processing within the computing environment.

    Abstract: Machine instructions, referred to herein as a long Convert from Zoned instruction (CDZT) and extended Convert from Zoned instruction (CXZT), are provided that read EBCDIC or ASCII data from memory, convert it to the appropriate decimal floating point format, and write it to a target floating point register or floating point register pair. Further, machine instructions, referred to herein as a long Convert to Zoned instruction (CZDT) and extended Convert to Zoned instruction (CZXT), are provided that convert a decimal floating point (DFP) operand in a source floating point register or floating point register pair to EBCDIC or ASCII data and store it to a target memory location.

    Abstract: Se proporciona una instrucción para realizar operaciones de conversión y escalado. La ejecución de la instrucción incluye convertir un valor de entrada en un formato para proporcionar un resultado convertido en otro formato. El resultado convertido se escala para proporcionar un resultado escalado. Un resultado obtenido a partir del resultado escalado se coloca en una ubicación seleccionada. Además, se proporciona una instrucción para realizar operaciones de escalado y conversión. La ejecución de la instrucción incluye escalar un valor de entrada en un formato para proporcionar un resultado escalado y convertir el resultado escalado desde un formato para proporcionar un resultado convertido en otro formato. Un resultado obtenido a partir del resultado convertido se coloca en una ubicación seleccionada. (Traducción automática con Google Translate, sin valor legal)

    Abstract: Negative zero control for execution of an instruction. A process obtains an instruction to perform operation(s) using an input value. The instruction includes a negative zero control indicator indicating whether negative zero control is enabled for execution of the instruction. The process executes the instruction, the executing including performing the operation(s) using the input value to obtain a result having a sign, determining whether to control the sign of the result, the determining being based at least in part on the negative zero control indicator being set to a defined value, and performing further processing, as part the executing the instruction, based on the determining.
