void = SetBoxTop(nFixedUnits)

This macro function is used to specify the top position of the textbox that contains the macro token.

➢Looking at the measurements palette of QuarkXPress and InDesign, as shown in the image on the right, the effect of this function is to set the value of Y equal to nFixedUnits, and to change the value of H so that Y+H remains unchanged.

➢Textbox resizing functions only work on textboxes whose angle is a multiple of 90 degrees (0­°, 90°, 180°, or 270°) and we strongly encourage you to always use non-rotated textboxes (with an angle of 0°) for any macro which contains the above macro function, as explained in the gridtemplate construction guidelines.

➢A fixed unit is the smallest unit of size, used by both QuarkXPress and InDesign, and is defined as 1/65536 of a point. This means that an inch is 4718592 fixed units, and a millimeter is approximately 185771 fixed units.

➢The value of the position you supply to this function must include the offset from the pasteboard to the top of the page, whose value differs between versions of QuarkXPress and InDesign, and can be obtained from the n_VerticalPasteBoardOffset system variable.

This function will affect the height of the textbox, depending on the value of nFixedUnits in comparison to the top position of the textbox before the function was called.
