assign — Assign a new value to a variable.
assign assigns a new value to a variable.
In the full text editor, an assignment is simply entered with the help of the assignment operator :=, 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 Input 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 Result gets the name of the variable, i.e., this
is the left side of assignment.
In addition to the parameter type control, which is indicated in the
parameter description, assign also supports iconic variables
and vector variables. For an assignment, the parameter types of the
two parameters Input and Result must be identical.
For the assignment of iconic objects, the operator copy_obj is
used internally.
Input (input_control) real(-array) → (real / integer / string)
New value.
Default: 1
Result (output_control) real(-array) → (real / integer / string)
Variable that has to be changed.
Tuple1 := [1,0,3,4,5,6,7,8,9] Val := sin(1.2) + cos(1.2) Tuple2 := []
If the expression is correct
assign returns 2 (
H_MSG_TRUE)
. Otherwise, an
exception is raised and an error code returned.
