Chapter 2 Command Codes

If the dot scale is selected, the parameters are specified in dot row and column. For example, based on a 60 dpi horizontal and 72 dpi vertical dot scale, a form of 8-1/2 x 11 inches has 792 rows (72 dpi x 11 inches) and 510 columns (60 dpi x 8-1/2 inches), and a form of 8 x 11 inches has 792 rows and 480 columns.

The default scale factor uses character row and column (6 lpi and 10 cpi). Anytime CP.DP format (page 26) is used, the scale assumes 6 lpi and 10 cpi and a 60 x 72 dpi format.

You can change the scale at any time during forms creation by using either of the Scale commands. Elements designed before the scale change will print at the former scale, while those elements following the scale change will print at the current scale.

Note For alphanumeric data, the Scale command only affects data position. For graphic elements (such as lines and boxes), the Scale command can also affect line thickness if the horizontal/vertical scales are given.
