Example Program


Location     Object Code                 Instruction

    0                             MAIN   CSECT

    4        5840 F018                   L      4,DEF
    8        1B55                        SR     5,5
    A        1A34                        AR     3,4
    C        1853                        LR     5,3
    E        5050 F01C                   ST     5,GHI
   12        07FE                        BR     14
   14        0000 0013            ABC    DC     F'19'
   18        0000 0057            DEF    DC     F'87'
   1C        F5F5 F5F5            GHI    DS     F
                                         END MAIN

We could rewrite all of this using only explicit addresses such as

     L   3,20(0,15)

instead of

     L   3,ABC

Notice that GHI was initialized for us by ASSIST to the value X'F5F5F5F5'.
