Which of the following are valid data definition statements that create an array of unsigned bytes containing decimal 10, 20, and 30, named myArray.

(A) myArray BYTE 10, 20, 30

(B) BYTE myArray 10, 20, 30

(C) BYTE myArray[3]: 10, 20,30

(D) myArray BYTE DUP (3) 10,20,30

(A) myArray BYTE 10, 20, 30

Explanation:

The general syntax of array declaration in assembly is given by

Array_Name TYPE value1, value2, ...

where type can be BYTE, WORD, DWORD, QWORD, REAL4 etc

where values can be in decimal, binary, or hexadecimal

Example:

Let us define an array of type unsigned byte and named myArray containing decimal values of 10, 20, and 30.

myArray BYTE 10, 20, 30

Hence only option A is the valid data definition.
