What is an .4TH file?

.4TH is Forth Language File

Language file created for Forth programming language, which is supported by several different text editors that enable features such as syntax highlighting; contains Forth programming code similar to how .C files contain C or C++ source code; same format as the .FORTH file.

Forth language's format is based on data stack and RPN (Revers Polish Notation). A simple example of its format:

12 10 * 40 + .
160 ok

This format equals to 12 multiplied by 10 plus 40, with "." printing the result of the mathematical equation to the user terminal.

NOTE: To create a 4TH file simply rename the extension of your plain text file that contains the Forth source code.
