Question

Which structure is the following true for?

_________ may have LOCAL labels.
O Neither Macros Nor Procedures
O Procedures
O Both Macros and Procedures
O Macros

Answer 1

In assembly language programming, the statement that 'may have LOCAL labels' is correctly applied to Macros. Local labels are internal to a macro and do not conflict with labels elsewhere in a program.

Step-by-step explanation:

The statement may have LOCAL labels.” is correctly completed by Macros. Macros can include labels that are only valid within the macro definition itself. These labels are known as local labels, and they are not accessible outside of the macro. In contrast, procedures generally utilize labels that are globally accessible within the entire code segment.

In the context of assembly language programming, macros are used to define a sequence of instructions that can be reused throughout a program. Macros can have labels within their definition that help in flow control, but once the macro is expanded into the actual instructions, these local labels do not conflict with the rest of the program’s labels. Procedures, on the other hand, are subroutines within a program that perform a specific task and are usually called multiple times.

Procedures can technically use local labels if the assembler or the programming language supports them, but typically they are designed to work with global scope to maintain clarity and consistency in call-and-return operations.
