| data | The name of a dataset, RECORD structure, a fully-qualified field name, or a constant string expression. |
| MAX | Specifies the data is variable-length (such as containing child datasets) and the value to return is the maximum size.. |
| Return: | SIZEOF returns a single integer value. |
The SIZEOF function returns the total number of bytes defined for storage of the specified data structure or field.
Example:
MyRec := RECORD
INTEGER1 F1;
INTEGER5 F2;
STRING1 F3;
STRING10 F4;
QSTRING12 F5;
VARSTRING12 F6;
END;
MyData :=
DATASET([{1,33333333333,'A','A','A',V'A'}],MyRec);
SIZEOF(MyRec); //result is 39
SIZEOF(MyData.F1); //result is 1
SIZEOF(MyData.F2); //result is 5
SIZEOF(MyData.F3); //result is 1
SIZEOF(MyData.F4); //result is 10
SIZEOF(MyData.F5); //result is 9 -12 chars stored in 9
bytes
SIZEOF(MyData.F6); //result is 13 -12 chars plus null
terminator
