BASIC CONCEPTSExample You placed the letter “A” at location (2,1). If you are measuringgrid units in inches, the origin of the “A” character cell is locatedtwo inches down and one inch to the right of the form origin. Ifyou are measuring the grid in cpi and lpi units, the origin of the“A” character cell is located two lines down and one characterwidth to the right of the form origin. At 10 cpi and 6 lpi, the “A”is .33 inches down from the form origin and .10 inches to theright.Negative coordinates Negative x and y values also may be used to place form elementsabove and/or to the left of the form origin, as long as the valuesare within system page boundaries.UNIT value The unit value of the GRID command specifies the unit ofmeasurement that the FDL commands use to position formelements on the page. Optionally, you can select a predefinedformat that automatically provides grid unit values. IndividualFDL commands may override GRID unit values.Predefined formatsA set of predefined print description entries or formats, havingstandard format specifications, is provided on the OperatingSystem Software (OSS) tapes. You may use the standard formatsor define your own to suit your specific needs.Reference Refer to the “Standard print formats” appendix for a list of thestandard LPS print formats.These standard formats provide commonly used impact printerconversion formats for use with specific page sizes andorientations. Use the Xerox design ruler to assist you inmeasuring character and line spacing. The ruler has eight scalesthat conform to the standard format grid.Reference Refer to the “Support tools and measurements” appendix formore information on the forms design ruler.FMT1 (landscape) or FMT6 (portrait) is used by FDL to providedefault values for page orientation, form origin, and grid unitdimensions, provided there are no explicit overriding parameters.Unless overridden by an explicit orientation PAGE SIZEparameter, the virtual page size in a predefined format is alwaysthe sysgen-specified paper size. The virtual page origin is locatedat the upper left corner of the physical page.XEROX 4050/5090/4450/4650 LPS FORMS CREATION GUIDE 1-13
