CharOne()

Removes duplicate adjacent characters from a string.

Syntax

CharOne( [<cDelete>], <cString> ) --> cResult

Arguments

<cDelete>

Passing a character string for <cDelete> restricts the search to the characters contained in it. The default removes all duplicate adjacent characters from <cString>.

<cString>

This is the character string to process.

Return

The function searches for duplicate adjacent characters in <cString> and removes them in the result string.

Note:  the function differs from CharList() which removes all duplicates. CharOne() removes only adjacent duplicates.
