08:59 ShakDiesel: how can i retrieve the 1st 4 characters of a name and if there is less than 4 all are shown?
09:03 bremner: I think there is a "take" function in srfi/13
09:04 bremner: ShakDiesel: ^
09:06 ShakDiesel: srry wat do you mean srfi/13
09:06 ShakDiesel: is that ref. to documentation?
09:08 bremner: http://docs.racket-lang.org/srfi-std/srfi-13.html
09:08 ShakDiesel: appreciate it thank you
09:09 bremner: ah, it seems string-take does not do what you want. It is not too hard to write a recursive function to do it, it is a typical exercise.
09:10 ShakDiesel: substring can acheive the 1st part but if there are less then 4 it does not adjust
09:11 bremner: what kind of adjustment do you want?
09:12 ShakDiesel: just the 1st 4 letters of "name" however if there are less than 4 then all are included
09:12 bremner: ok, I would suggest either write the short recursive function or look at format
09:13 ShakDiesel: sorry im fairly novice, by recursive u just mean a repeating function?
09:13 bremner: well, if you don't know recursion yet, then go for format.
09:14 ShakDiesel: ok
09:14 veer: ShakDiesel : you can also use string-length
09:14 bremner: it depends. is this homework that you are supposed to do some particular way?
09:15 ShakDiesel: yeah strings preferably
09:15 ShakDiesel: i just assumed (substring 0 4) would include less than 4 situations by putting the entire name
09:16 ShakDiesel: let me try string-length thx veer
