The DDS for the screen

Listed here are the DDS specifications used to define a typical subfile. It’s up to the developer to define the column headers and the fields used for each row of the subfile.

D* D* When filtering subfile loads using input fields on the control D* record, if no data is found or at EOF, DATASTATUS should be populated D* with @NOTFOUND while FILTERSTATUS is populated with @FILTERED.

D* D* The S1RRN fields are to be initialized with zero and are D* referenced by the WORKSTN file using SFILE(SF01SF:S1RRN). When D* the subfile is cleared, S1RRN should be reset to zero. During D* subfile loading, S1RRN is to be incremented by one for each subfile D* record written. D* D* The S1LINENBR fields are initialized differently. Subfile page D* loading is performed with a do-loop at which time S1LINE is zero. D* The do-loop is 'dou S1LINENBR = S1PAGE'. During subfile loading, D* S1LINE is incremented by one for each record written. D* D* S1RCDNBR is defined using the DDS keyword SFLRCDNBR seen on D* the subfile's control record. It is used to govern which page is D* seen after loads. To position to a page, specify that the page D* of the subfile to be displayed is the page containing the record D* whose relative record number is in this field. The default D* behavior is governed by moving S1LINE into S1RCDNBR after each load. D* D* In summary, S1PAGE is used by the program to determine if a full D* page has been loaded. S1RRN is defined on the F-Spec for the D* WORKSTN file to define the file's RRN field. It should not be used D* for anything other than for that purpose. Running parallel with D* this field is S1LINENBR which is used to control the load-loop. D* S1RCDNBR is used to control page positioning after loading. It may D* also be used to allow the user to control page positioning by D* moving the value supplied by a control record input field into D* S1RCDNBR.
