XENBLN/Commands

:
A list of all XENBLN commands as of October 23th, 2022.
This language was designed to have minimal errors.
If a command takes an integer or float/double as a parameter, it will try to convert those parameters to integers, but if that results in ñ (NaN, not a number), they will be turned into zero.
Similarly, if a command takes a string as a parameter, it will convert all those parameters to strings; or if it takes a Boolean value as a parameter, it will convert the parameter to false if it is 0, 0.0, "", f (false), û (undefined), or ñ (NaN), else it will convert it to Boolean true.
Therefore, it is not generally necessary to use type-casting functions unless you're using = (equality) or ≠ (inequality) or writing a switch statement case or for loop value to iterate over/number of iterations.
The 'O' command is now unnecessary except for outputting û (undefined) values, as all functions with return values other than û (undefined) automatically output their return values if they aren't themselves arguments to other functions, unless passed to ü (the 1-argument noop command), which returns û (undefined) and therefore prevents its argument from being output.
All variables (a, b, c, l, m, and n) are initialized to û (undefined).
Autocompletion and parameter filling: Strings, arrays, loops, functions, and function calls (see the next sentence) are autocompleted at EOF if they wouldn't be completed already. Also, missing parameters at EOF are set to û (undefined).
'X evaluates to (true/false)' really means 'bool(X) evaluates to (true/false)'.

Using variadic parameters (varargs) is not possible, but you could emulate this by using an array as a parameter.

42. * : (Arguments A, B) Returns A multiplied by B (the product of A and B; A * B).
43. + : (Arguments A, B) Returns A added to B (the sum of A and B; A + B).

The regex to match a switch statement is as follows: /Svaluecode((\{value)+code)*(¶code)?\}/, or for those who don't know regex, you start it with S, then follow it with {valuecode (the first time, don't put a {) where value is the value to be switched and see later down. You can do this as many times as you want before you put any code, but only if you leave it empty. For example, SI„A{„BO"You said A or B"} (with the C command, this can be shortened to SICACBO"You said A or B"}, or because of EOF autocompletion (strings and loops are autocompleted at EOF) even further to SI„ACBO"You said A or B) would match both "A" and "B". If you put a ¶code at the end, that code is the switch default, but is optional.

90. Z : (Arguments A, B) Returns bitwise AND(A, B).
91. [ : Start of array literal. For example, an array with "Foo", "Bar", 8, and Boolean false as its items would be written as ["Foo""Bar"8f]. Not to be confused with the Array.

120. x : Reserved for the current item in the for loop, or if the loop is set to loop n times with no iteration, it's equal to y; if the program is in a while loop, it's equal to the item used for the condition (used in 3-byte truth-machine); or if the program isn't in a for or while loop, it's equal to s. See also F.
