Demo Label showing use of Print Utility Procedures
After the file Pal_Procs_and_Formats.txt has been copied to the printer, a number of new procedures are now defined in the printer (until powered off). These procedures have been written specifically to demonstrate how to use the PALTM Print and Program operators to produce printed output. These procedures also provide easy ways to print various objects without actually needing to know the PALTM language. The print utility procedures may be incorporated into custom programming or just used as reference to better understand the PALTM Print and Program operators. After downloading Pal_Procs_and_Formats.txt to the printer, copy the file Proc_Demo.txt to the printer. This file uses the various print utility procedures defined to produce a demo label. Using a text editor, open the file Proc_Demo.txt file to see how these various utilities may be used as shown in the demo label print sample below.
The interesting thing to note in the Proc_Demo.txt file is that the only actual PALTM operator used is the showpage operator. The other procedure names used such as Printfont and Printbarcode are not native PALTM operators but new procedures defined. A careful study of the definition of these procedures will reveal the actual PALTM operators used.
The basics of creating procedures and using them in the PALTM language should start to make sense after reviewing how the procedures are defined (in Pal_Procs_and_Formats.txt) and how they can be used (in Proc_Demo.txt). New procedures performing virtually any task can now be written using the PALTM Print and Program Reference manual for detailed information on additional PALTM operators. The existing procedures may be modified as needed to meet requirements or completely new procedures may be written.
