Internally DBF Script 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. Like in Object Pascal, you can't 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).
