CHARONLY()
Intersectional set of two strings based on characters
Syntax
CHARONLY( <cThisCharactersOnly>, <cString> ) -> cReducedString
Arguments
<cThisCharactersOnly> specifies the characters that must not be deleted in <cString>. <cString> is the string that should be processed
Returns
<cReducedString> A string with all characters deleted but those specified in <cThisCharactersOnly>.
Description
The CHARONLY() function calculates the intersectional set of two strings. To do this, it deletes all characters from <cString> that do not appear in <cThisCharacterOnly>.
Examples
? CHARONLY( "0123456789", "0211 - 38 99 77" ) // "0211389977"
? CHARONLY( "0123456789", "0211/ 389 977" ) // "0211389977"
Tests
CHARONLY( "0123456789", "0211 - 38 99 77" ) == "0211389977"
CHARONLY( "0123456789", "0211/ 389 977" ) == "0211389977"
