CHARADD()
Adds corresponding ASCII value of two strings
- Syntax
-
- CHARADD (<[@]cString1>, <cString2>) --> cAddString
- Arguments
-
- <[@]cString1> first string <cString2> second string
- Returns
-
- <cAddString> string with added ASCII values
- Description
-
- The CHARADD() function constructs a new string from the two strings passed as parameters. To do this, it adds the ASCII values of the corresponding characters of both strings and places a character in the resulting string whose ASCII value equals to that sum (modulo 256). If the first string is passed by reference, the resulting string is stored in <cString1>, too. By setting the CSETREF()-switch to .T., the return value can be omitted. If <cString2> is shorter than <cString1> and the last character of <cString2> has been processed, the function restarts with the first character of <cString2>.
Examples
? charadd ("012345678", chr(1)) --> "123456789"
? charadd ("123456789", chr(255)) --> "012345678"
? charadd ("0000", chr(0)+chr(1)+chr(2)+chr(3)) --> "0123"
Tests
charadd ("012345678", chr(1)) == "123456789"
charadd ("012345678", chr(1)+chr(2)) == "133557799"
charadd ("123456789", chr(255)) == "012345678"
charadd ("123456789", chr(255)+chr(254)) == "002244668"
