### for

#### Synopsis

For ordinal index variables:

```     for ordinal_variable := initial_value to final_value do
statement
```

or

```     for ordinal_variable := initial_value downto final_value do
statement
```

For sets:

```     for set_element_type_variable in some_set do
statement
```

For pointer index variables:

```     for pointer_variable := initial_address to final_address do
statement
```

or

```     for pointer_variable := initial_address downto final_address do
statement
```

@@ Set member iteration

#### Description

The for statement is a count loop. For further information see for Statement.

#### Conforming to

for is defined in ISO 7185 Pascal and supported by all known Pascal variants. Iteration of Pointers is a Borland Pascal extension. Set member iteration is an ISO 10206 Extended Pascal extension.

#### Example

```     program ForDemo;
var
CharSet: set of Char;
c: Char;
n: Integer;
Fac: array [0 .. 10] of Integer;
PInt: ^Integer;
begin
CharSet := ['g', 'p', 'c'];
for c in CharSet do
WriteLn (c);  { prints `c', `g', `p' in three lines }
Fac[0] := 1;
for n := 1 to 10 do  { computes the factorial of n for n = 0 .. 10 }
Fac[n] := Fac[n - 1] * n;
{\$X+}
{ prints n! for n = 0 .. 10 }
for PInt := @Fac[0] to @Fac[10] do
WriteLn (PInt - @Fac[0], '! = ', PInt^)
end.
