A closer look, however, suggests that a rules-based approach is superior. 1  A good monetary policy rule specifies a plan of action which the central bank cannot later ignore, while discretion allows central bankers to reactâand often overreactâto economic indicators as they see fit.
A syntax error is an error in commands. For example, the following command: dir (path) which displays a directory in a Windows Command Prompt. The following, dir c:/windows/system32 would show the contents of the Windows/system32 directory in the C: drive.
Syntax refers to the spelling and grammar of a programming language. Computers are inflexible machines that understand what you type only if you type it in the exact form that the computer expects. The expected form is called the syntax. Each program defines its own syntactical rules that control which words the computer understands, which combinations of words are meaningful, and what punctuation is necessary to be a correctly structured document.
