ABSTRACT:
A variable under operator control is set to a desired value by taking a pause when the value of the variable has been modified such that it would surpass the desired value. Upon meeting the desired value, the value of the variable is set to the desired value for the duration of a pause period, during which the value of the variable remains fixed regardless of further attempts to modify the variable. Therefore, even if the operator is careless, the variable does not pass over the desired values. The variable may represent a voltage or current, or the position of a cursor.
