PowerBASIC Gazette #102
Subject: What is Transparent Unicode?
PowerBASIC has coined the phrase "Transparent Unicode" to describe the
implementation of this important character set in PB/WIN 10.0 and
PB Console Compiler 6.0. PowerBASIC uses the popular UTF-16 format,
where each character is represented by a 2-byte character code... a
DWORD in the range of 0 to 65535. This is the so-called "standard"
unicode format implemented by other programming languages as well.
In the past, the changeover to unicode was a bit rocky, at best. That's
because other compiler vendors took an "all or nothing" approach. Make
every string an ansi string, or make every string a unicode string. No
middle ground, just use one or the other. Even worse, some offered no
choice at all. Everything had to be unicode. No exceptions allowed.
That was difficult. Very difficult. How many times have we all saved
a numeric value in a string? That's the very reason MKI$() and CVI()
were invented years ago. And how about user-defined types? Storing
UDT data in a dynamic string is a perfect way to move it around easily.
But with forced unicode, these techniques are simply useless. In fact,
switching to unicode was a huge chore. Check out every string in every
module. Make certain there was no data which could possibly be corrupted
by unicode handling. No numerics. No UDT's. No special coding. And
don't ever try to do it again.
PowerBASIC knew there had to be a better way. Keep all the advantages
of ansi strings. Add all the benefits of unicode. All at once. In
fact, all in the same program. Just offer two complete categories of
strings: single-byte ansi strings, and two-byte unicode strings. How
do we identify them? One option is the typical TypeID character. As
always, single-byte ansi strings append the dollar-sign. The variable
named by xyz$ is a dynamic ansi string. But what if you want unicode?
Just append two dollar-signs, like the name abc$$. Of course, it may
be better to declare your variables explicitly. In this case, the name
of the string type includses a "w" to signify a wide unicode string.
LOCAL a AS STRING ' dynamic string - ansi
LOCAL b AS WSTRING ' dynamic string - wide unicode
LOCAL c AS STRING * 5 ' fixed length string - 5 ansi characters
LOCAL d AS WSTRING * 8 ' fixed length string - 8 unicode characters
LOCAL e AS STRINGZ * 5 ' nul-terminated string - 4 ansi chars + nul
LOCAL f AS WSTRINGZ * 8 ' nul-terminated string - 7 unicode chars + nul
LOCAL g AS FIELD ' field string - ansi field string
LOCAL h AS WFIELD ' field string - unicode field string
Yes, these names were specifically designed for symmetry. Prepend a
"W" to signify unicode. Remove the "W" for single byte ansi. It's
easy to use, easy to remember. But, for those who may have hundreds,
even thousands of declarations using ASCIIZ, we haven't forgotten you!
ASCIIZ will remain a synonym for STRINGZ for the forseeable future.
It's just that the term WASCIIZ would have been an oxymoron, at best.
How could we define an ascii string as wide unicode? Impossible.
So, what about Transparent Unicode? PowerBASIC handles all the messy
details for you! How about assignment and concatenation?
a$$ = "Hello"
b$ = a$$
c$$ = b$ + a$$
It's all automatic. PowerBASIC handles everything, so that each of
these code lines execute as expected. In the first line, "Hello" is
automatically converted to unicode, and then assigned to a$$. In the
second line, the contents of a$$ are converted to ansi, then assigned
to b$. In the third line, PowerBASIC automatically converts b$ to
Unicode format, appends a$$ to it, then stores the result in the
variable c$$. It's just that simple. Everything works just as in the
past, but your programs can now be unicode aware!
But is it fast? Of course! As always, PowerBASIC leads the way in
performance. It's very special. Just try the execution of an INSTR()
function against any other compiler on the planet. Unicode or ansi
or both. As with every time sensitive function, PowerBASIC keeps two
versions handy. One for OEM or ANSI, another for Unicode. Each of them
is built with explicit, hand crafted machine code. When it's time to
create your EXE, PowerBASIC includes only the one which best suits
Unicode is important today. It will be pervasive soon. With the
global growth of computer use, larger character sets are needed to
represent the necessary characters. We have clearly reached the point
where every programmer must consider alternate character sets for his
applications. Failure to do so can carry severe penalties. When you
find you can no longer read data files from an outside source, or can
no longer read text from the Internet, it will be too late. Give it
very close consideration today.
Books... Books... Books...
We now have books. PB/Windows 10 books. PB Console 6 books. We can
ship them to you today. Just in case you're interested in an official
PowerBASIC souvenir, we'll even sign your book with a personal message.
Just add a comment to your order...
These books are really huge. The PowerBASIC 10 for Windows Manual offers
more than 700 pages, and the PowerBASIC Console Compiler Manual isn't far
behind. They're packed with the information you need about PowerBASIC.
They're well made, with nice glossy covers to keep them looking fresh.
Not sure of the difference between COM and COMM? AUTOMATION and
DISPATCH? LET and SET? ANSI vs. ASCII vs. Unicode? Or maybe you
want to optimize with some inline assembler? Here's your chance to learn
without being tied to your PC. Books go anywhere!
Let's face it, online documentation can be handy... it gives us instant
context help, and we can lean back while it searches for us. But there
are always times when we'd just prefer to sit and read a printed book.
Books don't occupy screen space, so they don't cover up your code and
data in the IDE. Books are available on a plane, train, or armchair.
Regardless, I'm sure you'll find these books attractive and useful.
There are two new books available, one for PowerBASIC 10 for Windows,
the other for PowerBASIC Console Compiler 6. They're priced at just $49,
and they're available today.
On the same subject, keep in mind we still have DOS books available, too.
They're geared towards PowerBASIC 3.5 for DOS. These are offered as a
2-volume set, both User's Guide and Reference Guide, and priced at just
$29 for the set.
The POWER Changes Everything
Just in case you're one of the few... who hasn't yet upgraded to the
latest compilers -- Stay with me for a minute?
Now is the time to move. Full product purchases are just $199 and $169.
Pretty refreshing compared to some of the $2,000-$5,000 prices from the
competition! If you qualify for an upgrade, you can still take advantage
of special pricing. Upgrade PB/WIN 9 to PowerBASIC 10.0 for just $99 --
upgrade PB/CC 5 to PB/CC 6.0 for just $89! There is no reason to wait...
today is the day to upgrade.
Of course, PB/CC is our Console Compiler -- creates programs with a
text mode user interface. Easy to use. Easy to port from DOS. It's
the perfect solution for CGI Internet applications. Any time you want
pure performance and nothing more! PowerBASIC 10 for Windows gives you
the "look and feel" of a graphical user interface (GUI), the essence
of Windows. Frankly, they've both taken a big leap forward.
Static Link Libraries
Compile all your general purpose code into static units. Then, when
it's needed, just $LINK it into your EXE or DLL and you're on your way.
It's pre-compiled, so it's perfect for team programming. What will it
do for third-party tools? Plenty. PerfectSync has already released
SQL Tools 3. It links right into your EXE, so there's no need to drag
a DLL around. Just $LINK and go. Lots more tools are sure to follow.
And, if that's not enough, you'll get a librarian, too. Combine any
number of units to a single library, and just use one single $LINK.
PowerBASIC just discards those which aren't necessary. SLL's can
contain Subs, Functions, and Object Classes. How easy can it get?
Automatic Dead Code Removal
Fight the war on BloatWare. Now, you can include big libraries of
useful code -- PowerBASIC cleans it up for you. Any Sub/Function not
used is automatically ignored when compiled. In fact, even Classes
are pared down by similar Method and Property removal.
Order Now? GOTO https://shop.powerbasic.com/
The PowerTime Object is pretty special. It's a complete Date & Time
package for your applications. You can save and restore Date/Times.
Perform Date/Time arithmetic. Print formatted displays of Date/Time.
Calculate leap years, day-of-the-week, days-in-the-month and more.
What an opportunity to organize your program data. It's a lot like
an array, but with no bounds to constrain. Add items, remove them,
search for them by a "key" string, and more. Use them for random
access to the data, a linked list, a stack, a even a queue.
Ready now? GOTO www.powerbasic.com -- BUY NOW!
There's more. Lots, lots more. A completely new IDE based on Tabs,
with syntax display as you type! Transparent Unicode. Print Preview.
Thread Objects. A built in Resource Compiler. A StringBuilder Class.
PowerArray class encapsulates SafeArray structures. A DEC$ function
formats decimal numbers. Graphic Windows with scroll bars and scroll
keys, user drag to resize, clip areas, and wrap by whole word. ENUM
blocks, PREFIX blocks, ASMDATA blocks. THREADSAFE option for functions
and methods. TEXT windows, Text Split, and the new FASTPROC procedures.
There's more, but it's easy to see this is a very important upgrade.
SQL Tools version 3
You can use the power of SQL to access relational databases from
Microsoft Access, SQL Server, Oracle, FoxPro, dBase, Btrieve, and 50
other popular formats. Open a database with a single line of code,
and use standard SQL statements to build powerful, sophisticated,
multi-user database programs! This is a total database solution.
This product has earned accolades from virtually all of its users.
Version 3 is certainly no exception. With both a DLL and an SLL,
you'll have the option to just $LINK units and libraries right into
your EXE. No more DLL's to drag around, unless you choose it.
Even better, PowerBASIC will only link the code that's necessary.
Version 3 is faster and leaner, even with all the new features.
Many functions have been simplified. You can retrieve all rows in
a single operation. You'll also get improved trace files, Quad
integers, Unicode, plus enhanced Memo and BLOB field support.
Then there's improved Microsoft Access database support, and much
more! Documentation is provided in CHM, HLP, and PDF formats.
You can order right now...
PB/WIN 10.0 is priced at $199, while PB Console Compiler is $169.
Upgrades from versions 9 and 5 are just $99 and $89 respectively.
SQL Tools Pro is $199.95, while SQL Tools Std is $99.95. Upgrades
