CLEO Help Count letters in a long string

[monday]

Is there any simple way to do it? Plus is it possible to recognise and count capital+lower case letters within a string?

 

[monday]

If anyone was trying to find the same thing then below is how to check the number of letters within a string:
0AA7: call_function 0x00826330 num_params 1 pop 1 0@ 1@

0@ = input, stands for string
1@ = output, stands for number of letters/characters within a string

 

[Opcode.eXe]

0C17: 1@ = strlen 0@
