    Can't recognize these assembly instructions not x86 architecture instructions, please provide your OS, processor family & how did you get this code.

    EDIT: with little binging get to know it's Ibm System/370 architecture instruction set which is
    obsolete & I doubt you've access to one.

    This gets me to the assumption that you're on Windows with x86 family processor, So, use #-Link-Snipped-#, which uses X86 Instruction Listings.

    oh! yes you are right its not the x86 instruction set.
    Its in our course to study the IBM 360/370 instruction set that's why i want to know the meaning of these codes.
    Can you please ellobrate these codes.
