Why don't you try

Case (
IsEmpty ( Filter ( scope ; "LNC" ) ) ;
"Invalid parameter" ;

Let ( [
L = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" ;
N = "0123456789" ;
textTrimmed = Upper ( TrimAll ( theText ; 1 ; 3 ) ) ;
theFilter = Case ( scope = "L" ; L ; scope = "N" ; N ; scope = "C" ; L & N )
] ;
Length ( Filter ( textTrimmed ; theFilter ) )
)

)

// Args are: theText, scope

Thanks EOS for the shortend code, the character bit was for special character so i adjusted it a bit:

Case (
IsEmpty ( Filter ( scope ; "LNC" ) ) ;
"Invalid parameter" ;

Let ( [
L = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" ;
N = "0123456789" ;
textTrimmed = Upper ( TrimAll ( thetxt ; 1 ; 3 ) ) ;
theFilter = Case ( scope = "L" ; L ; scope = "N" ; N ; scope = "C" ; L & N )
] ;

If(thefilter=L & N;
Length(textTrimmed)-
Length(Filter(textTrimmed;thefilter));Length(Filter(textTrimmed; thefilter))

)

)

)
