Specifying print format parametersUsing LCDS Print Description Language 4-107• The MAIN and AUX stocks and their preferred trays havealready been defined in the operating system software whenthe printing system is delivered. However, you can changetheir specifications at the user interface, using the StockManager windows. (You cannot, however, delete them.)STOCKSET command exampleThe STOCKSET command is similar to the PDE and CMEcommands, because it produces a file you can compileseparately from the JDL. For each STOCKSET encounteredbefore an initial JDL or SYSTEM command, PDL creates a file ofthe type .STK, which contains information about the stockset.You can then reference the .STK file in multiple JSL source files.In the example above, a stockset called BILLS is created.• BILLS consists of four stocks: F1302, F1415, F6204, andF9999.• Stock references are created for these four stocks: COVERfor F1302, BODY and SUMMARY for F1415, LATE for F6204,and DISCON for F9999.• In the absence of a specific parameter of the FEEDcommand at the start of the report, INIFEED directs output tofeed from the stock referred to by COVER.• A system page will print on the stock referenced as COVER.You could use this stock set in a billing application by coding anOUTPUT STOCKS = BILLS command in the JDE. Throughsuccessive FEED DJDEs, the stock set directs feeding the cover,body and summary, late notice, and disconnect pages from thestock referenced by COVER, BODY, SUMMARY, LATE, andDISCON, respectively.Alternatively, the FEED DJDE record could refer directly tostocks by name, such as FEED= 'F1302'. Note that the use ofstock references is preferred over stock names, because stockreferences provide flexibility.BILLS: STOCKSET ASSIGN = ('F1302', COVER),ASSIGN = ('F1415',(BODY, SUMMARY)),ASSIGN = (('F6204', LATE),('F9999', DISCON)),INIFEED = COVER,/*INIFEED='F1302' works as well*/SYSPAGE = COVER;END;
