ASCII Table

mIRC: Scripting Language

ASCII stands for American Standard Code for Information Interchange. ASCII is a character encoding based on the English alphabet. ASCII codes represent text.

Base
The $base identifier can be used to convert a number from one base to another.

Numeral System	Base
Binary	2
Quaternary	4
Octet	8
Decimal	10
Hexadecimal	16
Duotrigesimal	32
Base 64 (Not Supported)	64

Using the table above you can convert any number form one base to the other

$base(<N>,<inbase>,<outbase>[,zeropad][,precision])
;N - Decimal Value 

;Let's convert the letter "A" to Binary
;We first need to find the decimal/ascii value of the letter
var %decimal = $asc(A)
;Now that we have it in decimal numeral system (Base 10, our inbase)
;we can convert it to Binary (Base 2, outbase) 
echo -a A -> $base(%decimal,10,2,8)
;A -> 01000001

Extended ASCII codes

Extended ASCII codes (128-255) were added later on. There are different variations to this set, perhaps the most common is the ISO 8859-1 set, which is what mIRC uses.

ASCII Printable Characters

echo -a $chr(<decimal number>)
echo -a $asc(<ascii value>)

Some characters like { and } are part of the language. As a result, using them in the $asc identifier will break it. You can prevent that by setting the character to a variable and referencing the variable. Since the $asc identifier will only convert the first char anyway, it is recommended to set the variable to the same char multiple time. Ex: {{ Instead of  {

echo -a $asc({)
* Too many parameters: $asc

var %a {{
echo -a $asc(%a)

ASCII Control Characters

The first 32 (0 to 31) char codes are reserve for control characters which were originally intended not to carry printable information, but rather to control devices.
