Chapter 6 Applied Instructions API 2207 Symbol: S ： Source value String D ： Conversion result Double word Explanation: 1. The IP address of the string type in S is converted into the IP address of the integer type, and the conversion result is stored in D . 2. The operand S occupies eight devices. 3. The IP address of the string type in S is divided into four sections. These sections are separated by “.” (16#2E), and there are three characters in every section. 4. The value converted from the characters in every section of the IP address of the string type in S can not be larger than 255. 5.
If S is a string, there are not necessarily three characters in every section of the IP address of the string type. For example, users can enter “192.168.0.1” instead of “192.168.000.001”.
