Direct mode, also known as immediate mode is a computing term referring to the input of textual commands outside the context of a program. The command would be executed immediately and the results printed on screen, in contrast to programming mode where nothing would be executed until a specific command was given (BASICs RUN is an example of a direct mode command.) Some commands could be used in either mode, others were exclusive to one or the other. Direct mode was most often used on 8-bit systems such as the Commodore 64 and Atari 800 series, though commands entered at a unix shell can be thought of as direct mode equivalents to shell scripts, and modern interpreted languages like Python and Perl include shells where commands may be entered for immediate evaluation and execution.

Famous quotes containing the words direct and/or mode:
“A fact is a proposition of which the verification by an appeal to the primary sources of our knowledge or to experience is direct and simple. A theory, on the other hand, if true, has all the characteristics of a fact except that its verification is possible only by indirect, remote, and difficult means.”
—Chauncey Wright (1830–1875)
“Literature exists at the same time in the modes of error and truth; it both betrays and obeys its own mode of being.”
—Paul Deman (1919–1983)
