Assembler Directives (cont)

Define Ten Bytes Define Word Assembler Directives (cont ) ASSUME Directive - The ASSUME directive is used to tell the assembler that the name of the logical segment should be used for a specified segment The 8086 works directly with only 4 physical segments: a Code segment a data segment a stack segment and an extra segment Example:

What are assembler directives 10 8086?
10. Assembler Directives 10 8086 Microprocessor An assembler is a program that is used to convert an assembly language program into an equivalent machine language program.
What is assemble directive?
The ASSUME directive is used to inform the assembler the names of the logical segments to be assumed for different segments used in the program .In the ALP each segment is given name. ASSUME CS:CODE,DS:DATA,SS:STACK
Why are machine codes only generated for assembler directives?
However, machine codes are only generated for the program that must be provided to the processor and not for assembler directives because they do not belong to the actual program. The assembler directives given below are used by 8085 and 8086 assemblers:
How many logical segments does a 8086 assembler use?
7. ASSUME DIRECTIVE ASSUME Directive - The ASSUME directive is used to tell the assembler that the name of the logical segment should be used for a specified segment. The 8086 works directly with only 4 physical segments: a Code segment, a data segment, a stack segment, and an extra segment.
