Internally FastScript operates with the Variant type and is
based on it. Nevertheless, you can use the following predetermined types
in your scripts:
Byte | Same as Integer type
Word |
Integer |
Longint |
Cardinal |
TColor |
Boolean | Boolean type
Real | Same as Extended type
Single |
Double |
Extended |
TDate |
TTime |
TDateTime |
Char | Char type
String | String type
Variant | Same as Variant type
Pointer |
Array | Array type
C++Script maps some types to standard types:
int, long = Integer
void = Integer
bool = Boolean
float = Extended
JScript has no types, all types are variants. BasicScript may
have types (for example, dim i as Integer), or may have no types
and even no variable declaration. In this case, a variable will have
Variant type.
Not all of these types can be assign-compatible. As in in Object
Pascal, you cannot assign Extended or String to an
Integer. Only one type - the Variant can be assigned to all the
types and can get value from any type.
Except the built-in types, you can use the enumerated types defined in
your application or in add-in modules (for example, after adding the
TfsGraphicsRTTI component, you can use TPenMode, TFontStyles
and other types).
