You mean i must do for example something like this:

Mystring var byte [24] ' maximal 24 bytes
String_Lenght var byte


But I must count how Long is my string from start $ to End Line feed.
For Example Ihave this $OK:CALL

String_Lenght for this example is 9 with Line feed

if Mystring[String_Lenght-2] = 76 then Character2 'L
Character2:
if Mystring[String_Lenght-3] = 76 then Character3 'L
Character3:
if Mystring[String_Lenght-4] = 65 then Character4 'A
Character4:
if Mystring[String_Lenght-5] = 67 then Character3 'C

and so on

but I think this is not the good way ,this is to complicated for several strings!
