CHARSWAP()
Swap neighbouring characters in a string
- Syntax
-
- CHARSWAP (<[@]cString>) -> cSwappedString
- Arguments
-
- <[@]cString> is the string that should be processed
- Returns
-
- <cSwappedString> a string where neighbour characters are swapped
- Description
-
- The CHARSWAP() function loops through <cString> in steps of two characters and exchanges the characters from the odd and the even positions. By setting the CSETREF() switch to .T., one can omit the return value of this functin, but one must then pass <cString> by reference.
Examples
? CHARSWAP("0123456789") // "1032547698"
? CHARSWAP("ABCDEFGHIJK") // "BADCFEHGJIK"
Tests
CHARSWAP("0123456789") == "1032547698"
