About data types (LotusScript Language)
LotusScript® recognizes the following scalar (numeric and string) data types:
| Data type | Suffix | Value range | Size |
|---|---|---|---|
| Byte | none | 0 to 255 | |
| Initial value: 0 | 1 byte | ||
| Boolean | none | 0 (False) or -1 (True) | |
| initial value: 0 | 2 bytes | ||
| Integer | % | -32,768 to 32,767 Initial value: 0 | 2 bytes |
| Long | & | -2,147,483,648 to 2,147,483,647 Initial value: 0 | 4 bytes |
| Single | ! | -3.402823E+38 to 3.402823E+38 Initial value: 0 | 4 bytes |
| Double | # | -1.7976931348623158+308 to 1.7976931348623158+308 Initial value: 0 | 8 bytes |
| Currency | @ | -922,337,203,685,477.5807 to 922,337,203,685,477.5807 Initial value: 0 | 8 bytes |
| String | $ | (String length ranges from 0 to 32K characters) Initial value: "" (empty string) | (2 bytes/character) |
Besides these scalar data types, LotusScript® supports the following additional data types and data structures:
| Data type or structure | Description | Size |
|---|---|---|
| Array | An aggregate set of elements having the same data type. An array can comprise up to 8 dimensions whose subscript bounds can range from -32768 to 32767. | |
| Initial value: Each element in a fixed array has an initial value appropriate to its data type. | Up to 64K bytes | |
| List | A one-dimensional aggregate set whose elements have the same data type and are referred to by name rather than by subscript. | Up to 64K bytes |
| Variant | A special data type that can contain any scalar value, array, list, or object reference. | |
| Initial value: EMPTY | 16 bytes | |
| User-defined data type | An aggregate set of elements of possibly disparate data types. Comparable to a record in Pascal or a struct in C. | |
| Initial value: Member variables have initial values appropriate to their data types. | Up to 64K bytes | |
| Class | An aggregate set of elements of possibly disparate data types together with procedures that operate on them. | |
| Initial value: When you create an instance of a class, LotusScript® initializes its member variables to values appropriate to their data types, and generates an object reference to it. | ||
| Object reference | A pointer to an OLE Automation object or an instance of a product class or user-defined class. | |
| Initial value: NOTHING. | 4 bytes |
In each of the preceding tables, the specified storage size is platform independent.
