使用する際の注意点

• Often used attributively; a macro language is the syntax for defining new macros; while macro expansion refers to the task of replacing the human-friendly version with a machine-readable version; a macro virus is a computer virus written in a macro language. Individual macros are sometimes referred to as macro functions, particularly when they accept parameters.
• The distinction between a macro language and a programming language is imprecise. Often a macro language is designed to allow one to customize one particular program, whereas a programming language is designed for writing entirely new programs.
• Whereas a shortcut is particularly easy to use, widely supported, and designed for normal users, macro systems are normally designed for power users.
