literal

(programming)
A constant made available to a process, by inclusion in the executable text. Most modern systems do not allow texts to modify themselves during execution, so literals are indeed constant; their value is written at compile-time and is read-only at run time.

In contrast, values placed in variables or files and accessed by the process via a symbolic name, can be changed during execution. This may be an asset. For example, messages can be given in a choice of languages by placing the translation in a file.

Literals are used when such modification is not desired. The name of the file mentioned above (not its content), or a physical constant such as 3.14159, might be coded as a literal. Literals can be accessed quickly, a potential advantage of their use.

literal

In programming, any data written into the program that remains unchanged when translated into machine language. Examples are values used for calculations as well as text messages displayed on screen. In the following lines of code, the literals are 1 and the value is one. See string literal and numeric literal.

if x = 1print "the value is one"endif

For this thorough understanding of the material read, the reader must therefore formulate two types of inferences: literal inferences, relating ideas within or between sentences, and implicit inferences, connecting ideas to complete information which is not explicit, incorporating prior knowledge and experience.
It was applied the reading comprehension evaluation protocol PROCOMLE [16], comprising four texts, as follows: two expository texts (Text E1 and Text E2) and two narrative texts (Text N1 and Text N2), each one comprising eight questions, four literal questions and four inferential questions, two related to microstructure and two to macrostructure of the text.

With this restriction, the expander can reconstruct the tree during decoding simply by hanging each new leaf from the node or arc indicated by the NodeCopy or LeafCopy codeword, or in the case of literals, by hanging the leaf from the permanent depth 1 node for each literal character.
