[Elecraft] Looking for an ASCII Elmer

[Phil Hystad]

ASCII...

Well, the UTF-8 character set is indeed designed to be backward compatible with ASCII but it is far more than that -- and even these days many programmers do have trouble with UTF-8.  Why?  Because UTF-8 is a multi-byte, variable length character encoding system.  Sure, the backward compatible ASCII codes are single byte but you can literally encode any character defined by UNICODE via UTF-8.  Chinese characters defined in UNICODE take more than a single byte to define so they require the multi-byte features of UTF.8.

Now, I do agree that the programming for radio control is not likely to run into multi-byte characters but UTF-8 will include them if they are found elsewhere -- say a text file that has mixed English as other multi-byte characters.

I agree with the need to download Xcode and learn Objective-C but the new Swift language might be easier for someone who is just starting out to learn.  I am not sure which would be easier to learn, Objective-C or Swift but I think Swift, being more modern and also supporting scripting is easier.

If that is to program the Mac, I highly recommend a tutorial on Objective-C and Cocoa, along with Aaron Hillegas’ excellent Mac programming tutorial “Cocoa Programming for Mac OS X” which is now in its fourth edition. I see that Aaron also has a book on Objective-C programming, which might be a good place to start. Both are produced by Big Nerd Ranch over in Atlanta, and are available from Barnes and Noble, amazon and other booksellers. Yu might also want to take a good look at programming the Mac in Swift. There are several good books available at the iBooks store, some free, others cost a bit. You might find Swift a bit easier than Cocoa to learn and get up to speed.

Time frame would be any time in March that suits both our calendars; probably by e-mail.  In case it matters, I use Mac OS X (10.10).
