    Abstract: A Vector Floating Point Test Data Class Immediate instruction is provided that determines whether one or more elements of a vector specified in the instruction are of one or more selected classes and signs. If a vector element is of a selected class and sign, an element in an operand of the instruction corresponding to the vector element is set to a first defined value, and if the vector element is not of the selected class and sign, the operand element corresponding to the vector element is set to a second defined value.

    Abstract: Processing of character data is facilitated. A Find Element Equal instruction is provided that compares data of multiple vectors for equality and provides an indication of equality, if equality exists. An index associated with the equal element is stored in a target vector register. Further, the same instruction, the Find Element Equal instruction, also searches a selected vector for null elements, also referred to as zero elements. A result of the instruction is dependent on whether the null search is provided, or just the compare.

    IPC: G06F9/30

    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.
