In computing, start is a command of the IBM OS/2, [1] Microsoft Windows [2] and ReactOS [3] command-line interpreter cmd.exe [4] (and some versions of COMMAND.COM) to start programs or batch files or to open files or directories using the default program. start is not available as a standalone program. The underlying Win32 API is ShellExecute ...
A commercial example would be the 1988 Norton Utilities Batch Enhancer (BE) command, where BE DELAY 18 would wait for 1 second, or the free 94-byte WAIT.COM [11] where WAIT 5 would wait for 5 seconds, then return control to the script. Most such programs are 16-bit .COM files, so are incompatible with 64-bit Windows.

[1] The various dialects of shell scripts are considered to be command languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing ...
Some programming languages, such as C, C++ and Java, allow a program to interpret the command-line arguments by handling them as string parameters in the main function. [ 21 ] [ 22 ] Other languages, such as Python , expose operating system specific API (functionality) through sys module , and in particular sys.argv for command-line arguments .
A high-level program (executing multiple programs, with some additional "glue" logic) is today most often called a script, and written in scripting languages, particularly shell scripts for system tasks; in IBM PC DOS and MS-DOS this is instead known as a batch file.
The source code comes with a 'complete.tcsh' file containing many examples of its completion syntax. Windows PowerShell, the extensible command shell from Microsoft, which is based on object-oriented programming and the Microsoft .NET framework, provides powerful and customizable completion capabilities similar to those of traditional Unix shells.
In the above example, the main( ) function defines where the program should start executing. The function body consists of a single statement , a call to the printf() function, which stands for " print f ormatted"; it outputs to the console whatever is passed to it as the parameter , in this case the string "hello, world" .
The language can be used to display information, set environment variables, start programs, connect to network drives, read or edit the registry, change the current drive and directory, and much more. With KiXforms, the user can create a GUI for KiXtart.
