The invention relates to novel binding domain-immunoglobulin fusion proteins that feature a binding domain for a cognate structure such as an antigen, a counterreceptor or the like, a wild-type IgG, IGA or IgE hinge-acting region, i. At least one icon set by the user to be displayed in response to detection of at least a predetermined amount of pressure on an actuated grip sensor is displayed depending on the detected touch position. The transaction code-attribute strings can include mask characters that act as substitution values. Multi-mode apparatus are also described. The independent subroutine is executed while the data is being retrieved from the backing store such that useful work is performed.
