The data type WSTRING is interpreted in Unicode format as opposed to the data type STRING (ASCII). As a result of this coding, the number of displayed characters for WSTRING depends on the characters. A length of 10 for WSTRING means that the length of the WSTRING can take a maximum of 10 WORDs. However, for some characters in Unicode, multiple WORDS are required for coding a character so that the number of characters do not have to correspond to the length of the WSTRING (10 in this case). The data type requires 1 WORD of memory per character plus 1 WORD of extra memory. Each STRING requires only 1 byte. The data type WSTRING is terminated with a ‎0‎.
