JScript .NET, Part I: The Mechanics

Compilation and Execution

Let's write the JScript .NET version of Hello World! Your program should include a single line:

print ("Hello World!");

Save this file as hello.js. Enter a Command Prompt window and type at the command line:

jsc hello.js

An executable file called hello.exe will be generated. Run the program by just typing the name of the executable (extension not needed) at the command line:

hello

You will get "Hello World!" in your Command Prompt window. Here is what the Command Prompt window looks like at this point:

The above scenario assumes that the location of the compiler jsc.exe is included in your path environment variable. Installing .NET SDK should take care of updating path. If the system does not find jsc.exe when you type jsc at the command prompt, you need to first find out where jsc.exe is. Do a search and find it. On my desktop, jsc.exe resides in C:\windows\Microsoft.NET\Framework\v1.0.3705. To add a directory to your path, right-click the My Computer icon on your desktop and select Properties from the shortcut menu. Select the Advanced tab and click the Environment Variables button. In the System Variables pane, select path from the list and click Edit. In the Edit System Variable dialog box, move the cursor to the end of the string in the Variable Value field and type a semicolon (;) followed by the full directory name found earlier for jsc.exe.

The compiler has several options. You can find them by using the /help or /? command line options, or by using the compiler without any options. To produce a .dll file instead of the .exe file you type:

jsc /target:library hello.js

To produce an executable with a different name, say welcome.exe:

jsc /out:welcome.exe hello.js

To generate debugging information in hello.pdb type:

jsc /debug hello.js
