If len is not specified, is is taken to be from the start to the end of the string. As shown in the code, ${2:0:1} will return the first character of the string; therefore, if $2 == 43340, then ${2:0:1} will return 4 (the first character of the string). ${2:1} will return 3340 (everything after the first character). The case statement makes it very easy to have a number of choices where only one choice runs. Either that or string together a lot of if..elif..else..fi rubbish.
