▶ TYL SYMBOLIZER
Tyl symbolizer turns regular ASCII characters combinations into special UNICODE symbols,
thus enabling Tyl code to be free from regular programming keywords.
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 software
entity or functionality.
Say we want to add a function: 'compare', that compares two numbers, we can write:
Say we want to add a function: 'compare', that compares two numbers, we can write:
compare num1 num2:
The colon character: ':', is Tyl code for a function declaration. Then when running the code,
Tyl symbolizer will replace the above code with:
compare num1 num2 »
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
The ternary statement:
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:
num1 >= num2 ? 1 \ -1
Tyl symbolizer will replace the above code with:
num1 >= num2 ? 1 ╌ -1
The symbol: '╌' is Tyl 'else' symbol. You can write code or symbol, because the system
will always turn codes into symbols.

compare function:
compare num1 num2 »
num1 >= num2 ? 1 ╌ -1
So if you want to write a Compare Test program, write:
main:
result1 compare 1 2
result2 compare 2 1
print result1
print result2
compare num1 num2:
num1>=num2?1 \-1
When running the program, the code will be replaced with this symbolized code:
main »
result1 compare 1 2
result2 compare 2 1
print result1
print result2
compare num1 num2 »
num1 >= num2 ? 1 ╌ -1
-1

Under the hood, Tyl Symbolizer is also responsible for inserting spaces before and after symbols, because spaces are
crucial in Tyl programs.
