I have a field in a file which is of alphanumeric type with a length of 15 and I'm going to store a string in that which is of 11 length and the string will be 'CAS00TST01A'. Now I want to extract the letter which is at 11th position i:e 'A' and i want to convert it to numeric. Could you please let me know which opcode will do this and ,if possible, could you post a sample code by declaring a field which is of alphanumeric type and passing the same value which I mentioned?
