2.2.1 Integer types

An integer type represents a subset of the whole numbers. The generic integer types are Integer and Cardinal; use these whenever possible, since they result in the best performance for the underlying CPU and operating system. The table below gives their ranges and storage formats for the current 32-bit Object Pascal compiler.

In general, arithmetic operations on integers return a value of type Integerhich, in its current implementation, is equivalent to the 32-bit Longint. Operations return a value of type Int64 only when performed on an Int64 operand. Hence the following code produces incorrect results.

var

I: Integer;

J: Int64;

...

I := High(Integer);

J := I + 1;

To get an Int64 return value in this situation, cast I as Int64:

...

J := Int64(I) + 1;

For more information, see Arithmetic operators.

Note:Most standard routines that take integer arguments truncate Int64 values to 32 bits. However, the High, Low, Succ, Pred, Inc, Dec, IntToStr, and IntToHex routines fully support Int64 arguments. Also, the Round, Trunc, StrToInt64, and StrToInt64Def functions return Int64 values. A few routinesncluding Ordannot take Int64 values at all.

When you increment the last value or decrement the first value of an integer type, the result wraps around the beginning or end of the range. For example, the Shortint type has the range *128..127; hence, after execution of the code

var I: Shortint;

...

I := High(Shortint);

I := I + 1;

the value of I is *128. If compiler range-checking is enabled, however, this code generates a runtime error.

2.2.2 Character types

Topic groupSee also

The fundamental character types are AnsiChar and WideChar. AnsiChar values are byte-sized (8-bit) characters ordered according to the extended ANSI character set. WideChar values are word-sized (16-bit) characters ordered according to the Unicode character set. The first 256 Unicode characters correspond to the ANSI characters.

The generic character type is Char, which is equivalent to AnsiChar. Because the implementation of Char is subject to change, it a good idea to use the standard function

SizeOf rather than a hard-coded constant when writing programs that may need to handle characters of different sizes.

A string constant of length 1, such as 'A', can denote a character value. The predefined function Chr returns the character value for any integer in the range of AnsiChar or

WideChar; for example, Chr(65) returns the letter A.

Character values, like integers, wrap around when decremented or incremented past the beginning or end of their range (unless range-checking is enabled). For example, after execution of the code

var

Letter: Char;

I: Integer;

begin

Letter := High(Letter);

for I := 1 to 66 do

Inc(Letter);

end;

Letter has the value A (ASCII 65).

2.2.3 Character types

Topic group

Delphi has three character types: Char, AnsiChar, and WideChar.

TheChar character type came from Standard Pascal, and was used in Turbo Pascal and then in Object Pascal. Later Object Pascal added AnsiChar and WideChar as specific character types that were used to support standards for character representation on the Windows operating system. AnsiChar was introduced to support an 8-bit character ANSI standard, and WideChar was introduced to support a 16-bit Unicode standard. The name WideChar is used because Unicode characters are also known as wide characters. Wide characters are two bytes instead of one, so that the character set can represent many more different characters. When AnsiChar and WideChar were implemented, Char became the default character type representing the currently recommended implementation. If you use Char in your application, remember that its implementation is subject to change in future versions of Delphi.

The following table summarizes these character types:

Type

For more information about using these character types, see "Character types*. For more information about Unicode characters, see "About extended character sets*.

2.2.4 Real types

Note:The six-byte Real48 type was called Real in earlier versions of Object Pascal. If you are recompiling code that uses the older, six-byte Real type, you may want to change it to Real48. You can also use the {$REALCOMPATIBILITY ON} compiler directive to turn Real back into the six-byte type.

The following remarks apply to fundamental real types.

Real48 is maintained for backward compatibility. Since its storage format is not native to the Intel CPU family, it results in slower performance than other floating-point types.

Extended offers greater precision than other real types but is less portable. Be careful using Extended if you are creating data files to share across platforms.

The Comp (computational) type is native to the Intel CPU and represents a 64-bit integer. It is classified as a real, however, because it does not behave like an ordinal type. (For example, you cannot increment or decrement a Comp value.) Comp is maintained for backward compatibility only. Use the Int64 type for better performance.

Currency is a fixed-point data type that minimizes rounding errors in monetary calculations. It is stored as a scaled 64-bit integer with the four least-significant digits implicitly representing decimal places. When mixed with other real types in assignments and expressions, Currency values are automatically divided or multiplied by 10000.

2.2.5 Boolean types

Topic groupSee also

The four predefined Boolean types are Boolean, ByteBool, WordBool, and LongBool. Boolean is the preferred type. The others exist to provide compatibility with different languages and the Windows environment.

A Boolean variable occupies one byte of memory, a ByteBool variable also occupies one byte, a WordBool variable occupies two bytes (one word), and a LongBool variable occupies four bytes (two words).

Boolean values are denoted by the predefined constants True and False. The following relationships hold.

Boolean

ByteBool, WordBool, LongBool

False < True

False True

Ord(False) = 0

Ord(False) = 0

Ord(True) = 1

Ord(True) 0

Succ(False) = True

Succ(False) = True

Pred(True) = False

Pred(False) = True

A value of type ByteBool, LongBool, or WordBool is considered True when its ordinality is nonzero. If such a value appears in a context where a Boolean is expected, the compiler automatically converts any value of nonzero ordinality to True.

The remarks above refer to the ordinality of Boolean valuesot to the values themselves. In Object Pascal, Boolean expressions cannot be equated with integers or reals. Hence, if X is an integer variable, the statement

if X then ...;

generates a compilation error. Casting the variable to a Boolean type is unreliable, but each of the following alternatives will work.

if X 0 then ...; { use longer expression that returns Boolean value }

var OK: Boolean { use Boolean variable }

...

if X 0 then OK := True;

if OK then ...;

2.2.6 String types

Topic groupSee also

A string represents a sequence of characters. Object Pascal supports the following predefined string types.

TypeMaximum lengthMemory requiredUsed for

ShortString255 characters2 to 256 bytesbackward compatibility

AnsiString~2^31 characters4 bytes to 2GB8-bit (ANSI) characters

WideString~2^30 characters4 bytes to 2GBUnicode characters;

COM servers and interfaces

AnsiString, sometimes called the long string, is the preferred type for most purposes.

String types can be mixed in assignments and expressions; the compiler automatically performs required conversions. But strings passed by reference to a function or procedure (as var and out parameters) must be of the appropriate type. Strings can be explicitly cast to a different string type (see Typecasts).

The reserved word string functions like a generic type identifier. For example,

var S: string;

creates a variable S that holds a string. In the default {$H+} state, the compiler interprets string (when it appears without a bracketed number after it) as AnsiString. Use the {$H directive to turn string into ShortString.

The standard function Length returns the number of characters in a string. The SetLength procedure adjusts the length of a string.

Comparison of strings is defined by the ordering of the characters in corresponding positions. Between strings of unequal length, each character in the longer string without a corresponding character in the shorter string takes on a greater-than value. For example, B* is greater than *; that is, 'AB' > 'A' returns True. Zero-length strings hold the lowest values.

You can index a string variable just as you would an array. If S is a string variable and i an integer expression, S[i] represents the ith character in S. For a ShortString or

AnsiString, S[i] is of type AnsiChar; for a WideString, S[i] is of type WideChar. The statement MyString[2] := 'A'; assigns the value A to the second character of MyString. The following code uses the standard UpCase function to convert MyString to upper-case.

var I: Integer;

begin

I := Length(MyString);

while I > 0 do

begin

MyString[I] := UpCase(MyString[I]);

I := I - 1;

end;

end;

Be careful indexing strings in this way, since overwriting the end of a string can cause access violations. Also, avoid passing long-string indexes as var parameters, because this results in inefficient code.

You can assign the value of a string constantr any other expression that returns a stringo a variable. The length of the string changes dynamically when the assignment is made. Examples:

MyString := 'Hello world!';

MyString := 'Hello ' + 'world';

MyString := MyString + '!';

MyString := ' '; { space }

MyString := ''; { empty string }

8.1.1 Do I need a form in the application server?

A:Yes. It doesn't need to be visible, but you do need one. To make the form not visible, set Application.ShowMainForm := False in the project file.

Q:After using the right-click to create the provider function, how can I re-execute the context menu option to "Export from Table"?

A:Once you have exported a provider interface, the context menu option is no longer visible. To re-display the context menu option you must delete the associated property in the Type Library Editor and press the Type Library Editors Refresh button. You should also delete the "Get_XXX" entry in the RemoteDataModule source.

Q:What is the difference between single and multiple instance application servers in a multi-tier application?

A: This can best be thought of from the point of view of the application server and how many clients can it support. One multi-instance server can support multiple clients.A single instance server can only support one client. Multi-instance servers create multiple data modules in one instance of the server. Single instance servers are launched for each client.

8.1.1 How do I locate the application servers available in the registry of the machine?

A: Read the registry key under HKEY_CLASSES_ROOT\CLSID\* looking for keys that have a subkey "Borland DataBroker". These entries are application servers. Here's an example that loads application server names to a Listbox.

procedure TForm1.FormCreate(Sender: TObject);

var

uses Registry;

I: integer;

TempList: TStringList;

begin

TempList := TStringList.Create;

try

with TRegistry.Create do

try

RootKey := HKEY_CLASSES_ROOT;

if OpenKey('CLSID', False) then

GetKeyNames(TempList);

CloseKey;

for I := 1 to TempList.Count - 1 do

if KeyExists('CLSID\' + TempList[I] + '\Borland DataBroker') then
