assignassignAssignassignAssignAssign (Operator)

Name

assignassignAssignassignAssignAssign — Assign a new value to a control variable.

Signature

assign( : : Input : Result)

Herror assign(double Input, double* Result)

Herror T_assign(const Htuple Input, Htuple* Result)

Herror assign(const HTuple& Input, double* Result)

Herror assign(const HTuple& Input, HTuple* Result)

void Assign(const HTuple& Input, HTuple* Result)

void HOperatorSetX.Assign(
[in] VARIANT Input, [out] VARIANT* Result)

static void HOperatorSet.Assign(HTuple input, out HTuple result)

Description

assignassignAssignassignAssignAssign assigns a new value to a variable.

In the full text editor an assignment is simply entered with the help of the assignment operator sign :=, e.g.:

  u := sin(x) + cos(y)

This is equivalent to the C syntax assignment:

  u = sin(x) + cos(y);

If the operator window is used for entering an assignment, assign must be entered into the operator combo box as an operator name. This opens the parameter area, where the parameter InputInputInputInputInputinput represents the expression that has to be evaluated to one value and assigned to the variable, i.e., this is the right side of the assignment. The parameter ResultResultResultResultResultresult gets the name of the variable, i.e., this is the left side of assignment.

Parameters

InputInputInputInputInputinput (input_control)  real(-array) HTupleHTupleHTupleVARIANTHtuple (real / integer / string) (double / int / long / string) (double / Hlong / HString) (double / Hlong / char*) (double / Hlong / BSTR) (double / Hlong / char*)

New value.

Default value: 1

ResultResultResultResultResultresult (output_control)  real(-array) HTupleHTupleHTupleVARIANTHtuple (real / integer / string) (double / int / long / string) (double / Hlong / HString) (double / Hlong / char*) (double / Hlong / BSTR) (double / Hlong / char*)

Variable that has to be changed.

Example (HDevelop)

Tuple1 := [1,0,3,4,5,6,7,8,9]
Val := sin(1.2) + cos(1.2)
Tuple2 := []

Result

If the expression is correct assignassignAssignassignAssignAssign returns 2 (H_MSG_TRUE). Otherwise an exception is raised and an error code returned.
