Just trying to understand. ããThere are several things { and } can be used for.ã1. To surround blocks of code that contain more than one statement, such as:ãif (x === 1)ã{ã console.print("x is 1");ã console.crlf();ã console.pause();ã}ãã2. When defining functions:ãfunction printNumber(num)ã{ã console.print(num);ã}ãã3. When defining objects:ãvar anObj = {ã aNum: 1,ã aString: "String"ã};ããThere may be more cases I'm not thinking of.ããNightfoxãã---ã þ Synchronet þ Digital Distortion: digitaldistortionbbs.comã

Thanks for the help my friend. I really don't know why I waited so long to get into js.ããSysOp: C.G.

Even so I would only expect you to end up one row above where you intended. Not sure what's up with that.ããFYI if your intention is to move to the first column of the last line in the terminal, I would recommend:ããconsole.gotoxy(1, console.screen_rows);ããThis will get you there no matter what the dimensions of the terminal are. (There is also a 'screen_columns' property.)ãã De> 2. - what are the { and } used for. As far as I can tell be reading up,ã De> they are only deed for condition statements. Just trying to understand. ããCurly braces do a few different things in JS, but mostly they're creating a 'block' to group several statements together. If your 'if' statement only needs to do one thing, then you don't need them:ããif (true) write('true');ããor even:ããif (true)ã write('true');ããIf your 'if' statement needs to do multiple things, you'll want them:ããif (true) {ã write('true');ã write('okay');ã}ããOtherwise the interpreter wouldn't know where the 'if' ended.ããSame goes for 'for' loops and probably a couple other things. In other places, they are mandatory, like when defining a function using the 'function' keyword.ããA lot more could be said on the subject, and somebody probably will, but I won't flood you with info just yet.ã ã--- ãechicken ãelectronic chicken bbs - bbs.electronicchicken.comã---ã þ Synchronet þ electronic chicken bbs - bbs.electronicchicken.comã
