       8 . The display control information generation method according to  claim 6 , 
 wherein the display user interface explicitly displays a position of a currently displayed sub-form with respect to the entire form.    
   
   
       9 . The display control information generation method according to  claim 6 , further comprising the step of: 
 providing a relevant sub-form among the sub-forms obtained by division with a hyperlink to a different sub-form.    
   
   
       10 . A computer for generating display control information for dividing and displaying a form in a style conforming to a terminal used by a user, the computer comprising: 
 request receiving means for receiving a form request from the terminal;    storing means for storing a screen definition of the form subjected to the form request and a code of validators for executing validation of an input value inputted into an input item in the form;    terminal capacity acquiring means for acquiring a terminal capacity of the terminal for displaying the form of the terminal;    dividing means for dividing the form in conformity to the terminal capacity acquired by the terminal capacity acquiring means by use of the screen definition of the form and the code of validators read out of the storing means; and    screen generating means for generating screen information to be displayed on the terminal by use of a result of division by the dividing means.    
   
   
       11 . The computer according to  claim 10 , 
 wherein the dividing means divides the form so as to prevent a size for one page after the division from exceeding an upper limit attributable to limitations of a screen size and a receive buffer of the terminal.    
   
   
       12 . The computer according to  claim 10 , 
 wherein the dividing means divides the form so as to prevent input items to be referenced by one validator from belonging to two or more divided forms.    
   
   
       13 . The computer according to  claim 12 , 
 wherein the dividing means divides the form so as to minimize the number of divided pages of the form.    
   
   
       14 . The computer according to  claim 12 ,
