  4. A full-stop is never used within the program, except when dealing with records (later topics) and at the end of the program as seen in the example above. The 'Var' keyword is used to introduce variables in a program to be used later on as temporary data storage elements. The variable names 'Num1', 'Num2' and 'Sum' in the program are data.

It is unlikely, for example, that armed with just basic knowledge from the preceding chapters, a novice programmer would be comfortable with the stuff about database programming. I've been using Pascal and its derivatives for thirty years, but am new to Lazarus, so I did learn a few tips This manual presents the simple multi-reader source code software in the Lazarus programming language.

Free Pascal (aka FPC Pascal or FPK Pascal) is a 32 and 64 bit Pascal compiler, written itself in Pascal.. Free Pascal is compatible with Borland Pascal 7 and most versions of Borland Delphi, but has number of additional features (operator overloading, function overloading, global properties, etc) Subject: [lazarus] Report Tools for Lazarus Hi all, we are in talks about the possibility to include LazReport as a component included in Lazarus, one of the questions that raised was if there are more Reporting Tools that work with Lazarus even if they can't be included, we would like to know.

The File Open modes are defined in SysUtils.pas as below. We can see that the fmOpenReadWrite is not as the same as fmOpenRead or fmOpenWrite. The fmShareExclusive specifies that the file cannot be read or write by other processes. The fmShareDenyWrite specifies that the file can by read but not write by other processes A full memory handling example: In this example, we'll build a new class that is a limited number list equivalent to the TStringList class. This class will allow you to keep adding numbers to a list of numbers. The class uses pointers to help store the numbers in a block of memory, reallocating this block when it is all used up Since programming languages are but tools, they comparatively may be better or worse-fitted for various kinds of programming tasks of all sorts. There may be better languages to do a particular kind of programming job now than the 5 mentioned, but all are still all widely in use and all have millions of lines of code out in the wild to maintain. Stream processing is a computer programming paradigm, equivalent to dataflow programming, event stream processing, and reactive programming, that allows some applications to more easily exploit a limited form of parallel processing.Such applications can use multiple computational units, such as the floating point unit on a graphics processing unit or field-programmable gate arrays (FPGAs.

The only special feature, if you are using ADO connections inside the Thread, is that you can't share the same connection.

As shown in Figure 19.2, the server program has two pages: one with a log and the other with a DBGrid showing the current data in the server database table. The client program is a form-based data entry, with extra buttons to send the data and delete records already sent (and for which an ID was received back) This doesn't really make much sense, but it is a good example to get started with. All vertices of our primitive (or object or scene) will go through this program. gl_Vertex is the current vertex which is being processed by this program. The vertex has the same (untransformed) values like you specify in glVertex3f(x,y,z) in your C++ program
