Get the text, start from the start_num bit, intercept the num_chars bit
LEFT - LEFT(text, [num_chars])
Get the text from the left num_chars so long

Find the substring within_text from the string find_text, start searching from start_num
Len byte length, returns the byte length of the string
Lenb - character length
