CHARRELA()
Correlates the character positions in paired strings
------------------------------------------------------------------------------
Syntax
CHARRELA(<cSearchFor1>,<cString1>,<cSearchFor2>,
<cString2>) --> nPosition
Arguments
<cSearchFor1> Designates the character that is searched for in
<cString1>.
<cString1> Designates the character string to search with
<cSearchFor1>.
<cSearchFor2> Designates the character that is searched for in
<cString2>.
<cString2> Designates the character string to search with
<cSearchFor2>.
Returns
CHARRELA() returns the positions where <cSearchFor1> and <cSearchFor2>
occur in the corresponding character strings.
Description
This function builds a relationship (CHAR RELAtion) between two
character strings. It determines the positions where the characters in
<cSearchFor1> appear in <cString1> and where the characters in
<cSearchFor2> appear in <cString2>.
Note
. The function returns a value of 0 if no relationship is found.
Example
Search for the first position in which a "b" appears in the first string
and a "1" appears in the second:
? CHARRELA("b", "b b b b", "1", "bbb11111") // 5
