assign_atassign_atAssignAtAssignAtassign_at (Operator)


assign_atassign_atAssignAtAssignAtassign_at — Assignment of one or several values to one or several tuple elements.


assign_at( : : Index, Value : Result)

Herror assign_at(const Hlong Index, const Hlong Value, double* Result)

Herror T_assign_at(const Htuple Index, const Htuple Value, Htuple* Result)

void AssignAt(const HTuple& Index, const HTuple& Value, HTuple* Result)

static void HOperatorSet.AssignAt(HTuple index, HTuple value, out HTuple result)

def assign_at(index: MaybeSequence[int], value: MaybeSequence[Union[int, float, str]]) -> Sequence[Union[int, float, str]]

def assign_at_s(index: MaybeSequence[int], value: MaybeSequence[Union[int, float, str]]) -> Union[int, float, str]


assign_atassign_atAssignAtAssignAtAssignAtassign_at assigns a single value to one or several elements of a tuple, or it assigns a number of values elementwise to the specified elements of the output tuple. All other elements of the output tuple keep their values. If the passed indices are out of the current range of the output tuple, the tuple is increased and the new values are initialized to a default value.

In the full text editor an assign_atassign_atAssignAtAssignAtAssignAtassign_at operation is simply entered with the help of the assignment operator symbol := and the index access operator symbol [ ] following the output variable. The IndexIndexIndexIndexindexindex parameter can be any expression that evaluates to any number of positive integer values. The ValueValueValueValuevaluevalue parameter must evaluate to exactly one value or to the same number of indices that are provided via the IndexIndexIndexIndexindexindex parameter, e.g.: Areas[Radius-1] := Area Areas[0,4,|Rad|-1] := 0 FileNames[0,2,4] := ['f1','f2','f3']

The operator assign_atassign_atAssignAtAssignAtAssignAtassign_at replaces and extends the modifying version of the old insertinsertInsertInsertInsertinsert operator.

If the expression is correct assign_atassign_atAssignAtAssignAtAssignAtassign_at returns TRUE. Otherwise, an exception is raised and an error code returned.
