Editing Transclusion (section)

{{unsourced section|date=July 2024}}
A common feature in programming languages is the ability of one source code file to transclude, in whole or part, another source code file. The part transcluded is interpreted as if it were part of the transcluding file. Some of the methods are:
* Include: Some programs will explicitly INCLUDE another file. The included file can consist of executable code, declarations, compiler instructions, and/or branching to later parts of the document, depending on compile-time variables.
* Macro: [[Assembly language]]s, and some high-level programming languages, will typically provide for macros, special named instructions used to make definitions, generate executable code, provide looping and other decisions, and modify the document produced according to parameters supplied to the macro when the file is rendered.
* Copy: The [[Cobol]] programming language has the COPY command, in which a copied file is inserted into the copying document, replacing the COPY command. Code and declarations in the copied file can be modified by a REPLACING argument as part of the copying command.
