The input method subroutines are written by you, and then their names are specified as arguments to Toolkit subroutines (such as I_FLDMOD or IB_FIELD) or the .FIELD script command. UI Toolkit then calls them at the appropriate time.
Method subroutines are important in applications that will run in a Windows environment.
