For instructions on how to do this on Windows XP, refer to Microsoft KnowledgeBase 310519: How To Manage Environment Variables in Windows XP. NOTE: If you use an interpreter other than ActivePerl, ActivePython and ActiveTcl, you may have to manually set up your Path environment variable to point to the interpreter’s executable.

Make sure that the TCL extension is now associated with Tclsh Application.

Click the OK button on the Open With dialog.

On the Opens With dialog, click Browse and select the ActiveTcl command line interpreter, tclsh.

The Opens with details defaults to Wish Application.

On the Registered file types listbox, scroll down to the extension TCL and select it.

tcl file association to the Tcl command line interpreter.

The following direction will step you through pointing the. tcl file association to point to the Tcl command line interpreter - tclsh. In order to run your Tcl scripts directly from the command line, you need to modify the. tcl files with a windows shell interpreter - wish - rather than a command line interpreter. One caveat to be aware of is that, by default, ActiveTcl will associate. tcl) with their interpreters so that you can run the script directly by calling its filename. In addition, they will also set up file associations with the file extension (.pl. One of the benefits of using ActiveState’s interpreters is that the installers will automatically set up the computer’s Path environment variable so that you can call your scripts from any directory.

The first step in running a script is downloading an interpreter that will take your script and convert it into machine level language.įor our tutorials and examples, we used ActiveState’s free interpreters for Perl, Python and Tcl: Running Scripts Installing an Interpreter Python: Named after the BBC show “Monty Python’s Flying Circus” Perl: Stands for Practical Extraction and Report Language This can reduce the likelihood of memory leaks occurring.

Garbage Collection: Most scripting languages automate garbage collection (freeing of memory used by data).

Native Complex Types: Most scripting languages also natively provide certain complex data types like strings, arrays, lists and hashes.

While this can make it easy to run into typecasting errors, it makes the language easier to learn and can improve the readability of the script.

Typeless: Variables can be used to hold any type of data without having to explicitly declare their type.

While this leads to a performance hit as each line has to be interpreted on the fly, it makes for easier portability between systems.

Interpreted: Scripting languages are typically converted into machine-level code during runtime by an interpreter, rather than being compiled into an executable before running.While there is no fixed definition of what constitutes a scripting language, some of the common distinguishing traits of these languages include: Scripting languages are programming languages that are typically written using high-level programming constructs, which makes them easy to learn. Mention this as it sounds like what you ran in to above.Introduction What is a scripting language? This is a major pain, but I don't know of any way around it.
