Test: Assembler Directives And Operators - Computer Science Engineering (CSE) MCQ

These directives help the assembler to correctly understand the assembly language programs to prepare the codes.

In ALP, each segment is given a name by using the directive ASSUME
SYNTAX: ASSUME segment:segment_name
Eg: ASSUME CS:Code
here CS is the Code segment and code is the name assumed to the segment.

 These directives are used for allocating memory locations in the available memory.

The directive END is used to denote the completion of the program.

The directive ENDS is used to end a segment where as the directive END is used to end the program.

The directive updates location counter to next even address if the current location counter contents are not even.

 If an ORG is written then the assembler initiates the location counter to keep the track of allotted address for the module as mentioned in the directive.
If the directive is not present, then the location counter is initialised to 0000H.

The directive SEGMENT indicates the beginning of the segment.

 In this, the recurring/repeating value is assigned with a label.The label is placed instead of the numerical value in the entire program code.

The labels, constants, variables, procedures declared as GLOBAL can be used by any module in the program.
