Tyl software does not use keywords. Instead of keywords, you write combinations of one or more ASCII characters, referred to as the code, and the symbolizer is turning them into special symbols, referred to as the symbol, that represent a programmatic value or functionality.

Say we want to add a compare function, that compares two numbers, we can write:

The colon character ':', is Tyl code for a function declaration. Then when running the code, Tyl Symbolizer will replace the above code with:

The symbol '»' is Tyl function symbol. You can use it also in your Tyl code.

Now we want to compare the numbers and return 1 if num1 is greater than or equal to num2, else return 1. We can use the ternary operator that is composed of a question mark and of the backslash character '\' ,the else code.

The ternary statement:

Tyl Symbolizer will replace the above code with:

The symbol '⇋' is Tyl else symbol. You can write code or symbol, because the system will always turn codes into symbols.

The full compare function:

So if you want to write a Compare Test program, write:

When running the program, the code will be replaced with this symbolized code:

Under the hood, Tyl Symbolizer is also responsible for inserting spaces before and after symbols.
