Sorry, you would have to mindread or ask the specific implementator[s]. > Is there logic that can not be resolved without a break in loop? No. The if-statement can always be used, but proper modular programming gives better logic. ====================== Edsger Wybe Dijkstra was from the 1960s the main proponent for "Structured programming" [the word "modular" probly was not coined yet in this sense]: 1968 on a typewriter: "Go-to statement considered harmful, A case against the Go To statement" <http://www.cs.utexas.edu/users/EWD/ewd02xx/EWD215.PDF> Wiki: <https://en.wikipedia.org/wiki/Edsger_W._Dijkstra> <https://en.wikiquote.org/wiki/Edsger_W._Dijkstra> -- Evertjan.
