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?
Assembler Directives (cont..) Defined Byte. 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.
What is a segment directive?
and simplified segment directives, the directive in your program instructs the assembler to start a code segment. The next segment directive closes the previous segment; the directive at the end of your program closes remaining segments.
What are the basic assembler directives for 8086?
The following section explains the basic assembler directives for 8086. The various directives are explained below. 1. ASSUME : The ASSUME directive is used to inform the assembler the name of the logical segment it should use for a specified segment.
Will assembler ignore a statement after an end directive?
The assembler will ignore any statement after an END directive. Carriage return is required after the END directive. ENDS - This ENDS directive is used with name of the segment to indicate the end of that logic segment.
