function evalmcw(editHndl);
%EVALMCW Evaluates a list of functions in a editable text uicontrol.
%   EVALMCW stands for "Evaluate MATLAB command window".
%   EVALMCW(editHandle) evaluates the MATLAB code inside the editable
%   text uicontrol object referred to by the handle editHandle.
%   If an error is detected in the code, it will display the error
%   in the edit field and then reset the text to the last legal
%   statement executed.
