Hi, ...still improving my shortwave-broadcaster-dumper... :)
I have a list with sublists of strings, which I want to concatenate. Each sublist shall form one line of output. I tried 'string-append', but this gives me something like this (excerpt): "189RikisutvarpidRas1+20000-24001234567Icelandic" ...the separating #\space is missing. The according code looks like this (excerpt) (apply string-append sublist) then I found 'string-join' which has extra-parameters to define separator of all kinds. ...but...how can I express the 'apply'-instruction...with the addional parameters??? This looks something inbetween funny and weird: (apply string-join sublist " ") and racket mumbles: apply: contract violation expected: list? given: " " argument position: 3rd other arguments...: #<procedure:string-join> ?
