RESET statement


Set a scalar (non-array) variable, Variant, User-Defined Type, individual array element (or an entire array) to zero or null/empty.  RESET does not deallocate the actual memory used (with the exception of dynamic string array data, which is automatically deallocated).


RESET variable [, ...]

RESET array() [, ...]

RESET array(index) [, ...]


If variable is numeric, it is set to zero.  If variable is a dynamic string, it is set to null (""; an empty string).  If variable is a nul-terminated string, the first byte is set to nul ($NUL).  If variable is a fixed-length string or User-Defined Type/Union, all bytes in variable are set to nul, or CHR$(0).  If variable is a Variant, it is cleared and set to data type %VT_EMPTY.

If array() is numeric, all elements are set to zero; otherwise all elements are set to zero/null.  If an array index value is specified within the parentheses, just that array element is set to zero/null, as if it were a scalar (non-array) variable.

RESET also works with absolute arrays, clearing the contents to zeroes or empty strings.  For more information on absolute arrays, please refer to the DIM statement.
