Explain the Statements Present in Assembly Language
An assembly program consists of subsequent three types of statements:
a. Imperative statements: this point out an action to be carried out during execution of the assembled program. Every imperative statement usually translates into one machine instruction.
b. Declaration statements: The syntax of declaration statements is like this:
[Label] DS
[Label] DC ‘’
The DS statement reserves areas of memory and links names with them.
The DC statement constructs memory words containing constants.
c. Assembler directives: These instruct the assembler to carry out specific actions during the assembly of a program. For instance
START directive points out that the first word of the target program generated by the assembler should be placed in the memory word along with address .
