for below instance,
Code:
          WTO   'HELLO WORLD!'
+         CNOP  0,4
+         BAL   1,*+20
+         DC    AL2(16,0),C'HELLO WORLD!'
+         SVC   35


Where Can I find the usage of DC?

I don't quite understand how below instruction performs.
+ DC AL2(16,0),C'HELLO WORLD!'


Thanks for your advice.

Thanks.

It seems that Assembler is more complicated than advanced languages.

Complication sometimes means just (a lot) more simple steps.

the real thing that I cannot stand in C is the pointer arithmetics
( all the casting to be done to increment the way I want not the way that C wants really bothers me )
