== CHAR type variables ==
{{anchor:char}}
**CHAR** (//character//) types are suitable for storing a single letter each. The original CHAR uses codes from the ancient **ASCII** character mapping table. This table contains a mix of 255 different characters (letters, numbers, control characters, graphic symbols). Its advantage is that it requires only 1 byte, but its disadvantage is that the character set is quite limited; for example, Hungarian or Chinese accented characters are mostly excluded.

The extended version of CHAR is **WCHAR** (wide-character), which has a 2-byte length but can be used more broadly with its (**UNICODE**) //UCS-2// mapping. Up to 65,535 character mappings can be encoded with 16 bits; UNICODE does not fully utilize this range.

When declaring an operand of data type WSTRING you can define its length using square brackets (for example WSTRING[10]). If you do not specify a length, the length of the WSTRING is set to 254 characters by default.

== Special characters ==
A character string can also contain special characters. The escape character $ is used to identify control characters, dollar signs and single quotation marks.
