Numeric Variables153• Amersand (&) (HEX 26)The SFCC can also be used as part of a form or logo name.Numeric VariablesSome command parameters may include numeric variables. When it isrequired, an appropriate numeric value must be entered. In optionalparameters where a numeric variable appears, the numeric variable needs tobe included only if the option is selected.CommentsComments that aid in preparation or maintenance of a form or logo may beadded to command lines that do not contain the SFCC. They must bepreceded by a slash (/).Print Position LocationPGL provides a method of placing the print position at any location on a pageby selecting a character column or row, and a dot position within the specified(starting or ending print location) character cell. In commands that initiateprinting of alphanumeric characters, barcodes, etc., there are optionalmethods you may use to select a vertical character column and dot position,and a horizontal character row and dot position.When selecting a vertical character column and dot position, the format is thesame as for selecting horizontal character row and dot position. The row orcolumn is defined first followed by the dot position. The only differencebetween the two is the range of allowable dot positions.Each character cell is 6 dot columns wide (0-5) by 12 dot rows high (0-11).The format for specifying character cell (in a row or column) and dot position(within the specified character cell) is as follows:XX, YYwhere:XX = Character Column or RowYY = Vertical or Horizontal Dot PositionNOTE: A column and row position (two XX.YY selections) must be specifiedto locate the specific character cell where printer output will beginand/or end.The decimal point must be present when specifying dot positionswithin a cell.Within the command structure the starting row is defined first followed by thestarting column.This same format can be used to specify the distance between duplications ofa specific element on a form horizontally and vertically. In this case the rowand dot position indicate how far to move to the next print position.(See “Horizontal Duplication Command” on page 167 and “VerticalDuplication Command” on page 168 for examples).
