A program designed to execute a set of interrelated tasks. Typically referring to a system designed to address a particular business purpose (e.g., Order Entry/Inventory/Invoicing, a document tracking database, or an insurance claims calculator).
Environment Variables :
Operating system variables that can be used to communicate configuration information to executable programs. Environment variables are manipulated using the DOS SET command. The Clipper language compiler and linker respond to certain environment variables. Clipper programs can inspect the settings of environment variables using the GETENV() function.
Executable File :
A file output from the linker directly executable from the operating system command line. Executable files have an .EXE extension.
See Also: Linker
Header File :
A source file containing manifest constant definitions; command or pseudofunctions; and/or program statements merged into another source file using the #include preprocessor directive.
See Also: Program File, Source Code, STD.CH
Library File :
A file containing one or more object modules. The linker searches specified libraries to resolve references to functions or procedures that were not defined in the object files being linked.
See Also: Linker, Module, Object File
Make File :
A text file used as input to a make utility containing the specifications and actions required to build a program or a system of programs. This file is often referred to as a description file.
See Also: Make
Object File :
A file that contains the output of a compiler or other language translator, generally the result of compiling a single source file. Object files are linked to create an executable program.
See Also: Linking, Program File
Procedure File :
An ASCII text file containing Clipper language procedure and function definitions usually ending with a (.prg) extension; a program file.
See Also: Program File
Program File :
An ASCII text file containing Clipper language source code. Program files usually end with a (.prg) extension. The compiler reads the program file, translates the source code, and produces an object file, that is then linked to produce an executable program.
See Also: Linking Object File Source Code
Script File :
A text file that contains command input to a compiler, linker, or other utility program. A script file is often used in lieu of equivalent keyboard input. For the Clipper compiler, script files contain a list of source files to be compiled into a single object file.
Source File :
A text file including source code.
