3. Using HFDL commands
You use the Host Forms Description Language (HFDL) keyword
commands to translate your form design into a format for the
host computer. The command set representing your form
becomes the Forms Source Language (FSL), which the host
compiles and stores. You can download the compiled form to a
Xerox LPS or XES printer. This chapter describes the HFDL
commands and their functions.
Creating forms with HFDL commands
The HFDL command language syntax is usually the same as the
Forms Description Language (FDL) command language syntax.
You should be familiar with the FDL commands and how to use
them at the printer.
For more information on FDL commands and printer usage , refer
to the Xerox Laser Printing Systems Forms Creation Guide and
the “Troubleshooting syntax errors” section in the HFDL Release
Notes.
The “Comparison of HFDL and FDL” appendix in this manual
compares the commands for HFDL 2.1D, HFDL 3.1, HFDL 3.2,
and FDL.
