Marque de racine (radix mark)

Pascal uses the . (dot) to separate the integer and fractional part in literal decimal integers.

myReal := 6.28318

At least one digit in front of the period is mandatory. A 0 integer part must not be omitted.

Numbers noted in a non-decimal base can not be noted in that way. E. g. the numeric value “a half” can not be written as %0.1 (% being the prefix marking binary numbers).

Sélecteur de portée d'un identificateur

For structured data types the dot separates the data structure identifier from its individual components, i. e. methods or data fields.

 1 program recordDemo(input, output, stderr);
 2 
 3 uses
 4 	Linux;
 5 
 6 var
 7 	info: TSysInfo;
 8 begin
 9 	if sysInfo(@info) <> 0 then
10 	begin
11 		halt(1);
12 	end;
13 	
14 	writeLn('uptime: ', info.uptime, ' seconds');
15 	
16 	with info do
17 	begin
18 		writeLn('total free: ', freeram, ' bytes');
19 	end;
20 end.

Etendue

Two consecutive dots .. let you specify an ordinal type sub-range.

type
	signumCodomain = -1..1;

This is the same as math.TValueSign.

Fin de module

The main block of any module, i. e. program, unit or library, has to be closed with an end “dot”:

program hiWorld(input, output, stderr);

begin
	writeLn('Hi world!');
end.

It can be seen as an adoption of natural (written) languages, where a full stop marks an end of a sentence.

Anything else after the final end., assuming syntactical correctness, will be ignored by the compiler.

Espace de nom

Unit names containing dots create namespaces.

Valeur ASCII

In ASCII, the character code decimal 46 (or hexadecimal 2E) is defined to be . (full stop).
