You specify the DC instruction to define the data constants you need for program execution. The DC instruction causes the assembler to generate the binary representation of the data constant you specify into a particular location in the assembled source module; this is done at assembly time.

Move alphanumeric fields using the MVC instruction,. •. Define alphanumeric In IBM System/360 through present day z/Architecture, an address constant or "adcon" is an assembly language data Address constants are defined using an assembler language "DC" statement. a four bit general register number and a twelve bit displacement, the same format as addresses are encoded in instructions. Machine instructions generate machine code, assembler directives do not. DC.B - Define constant in memory of length one byte. This assigns a memoryThere are two specific classes of non–executable instructions: declaratives and .. The two primary data definition statements are the DS directive and the DC ii Assembler Language Programming for IBM System z™ Servers Lecture Slides Section 11 describes the Assembler?s basic data definition instruction, DC. The symbol table allows each symbol to have a program type and an assembler type assigned. The DC and DS assembler instructions allow you to specify a The character constant specifies character strings, such as error messages, identifiers, or other text, that the assembler converts into binary representations. Understand the basics of assembler programming on System z. – Use a variety of . Instruction address – this is the address of the next instruction to be executed. ? GPRs and FPRs .. Data is defined via the DC and DS HLASM directives.
