print over the current line, and is a technique impact printers use to print a line, or
elements of a line, in bold or with underlining. For example, the input data for an
impact printer might underline text by placing the text to underline on one line, and
the underscore characters of the underline on the following line. The first character
of the line with the text is a code that tells the printer to ignore the LF at the end of
that line. The result is underlined text.
It is important to understand what happens when you tell the channel skip emulation
in PlanetPress Design to ignore the LF at the end of a line. Recall that the emulation
stores each line of data in the data page buffer, and that each cell of the data page
buffer can contain at most a single character. If the emulation ignores the LF at the
end of a line, it must determine whether to overwrite the cells of the last line of data it
stored. In this case, it compares the character in each cell in the line with the one in
the new line destined for that cell. If the character in the cell is a space or an
underscore, it overwrites that character with the one from the new line. If the
character in the cell is not a space or an underscore, it leaves it intact.
l
Skip x lines: Use these boxes to enter any channel skip codes in your data that tell
the document to skip a specific number of lines. If you want to enter a backslash
character (\) as a code, you must precede it with another backslash character (thus
you would enter \\). You can also specify an ASCII character as a code using its
octal value preceded by a backslash (for example, \041 is the exclamation mark
character [!]).
l
Char, Skip to line: Use these boxes to enter any channel skip codes in your data
that tell the document to skip to a specific line. Enter the code in the Char box; enter
the line number in the Skip to line box or use the spin buttons to adjust its value. If
you want to use a backslash character (\) as a code, you must precede it with
another backslash character (thus you would enter \\). You can also specify an
ASCII character as a code using its octal value preceded by a backslash (for
example, \041 is the exclamation mark character [!]).
l
Go to column: Use this to enter the channel skip code in your data that tells the
document to advance to a specific column. Enter the code in the Char box to the left
of the Go to column label, and use the box on the right of the Go to column label to
set the column number. This is useful when your data contains redundant lines that
were originally created to bold a line on a line printer. By entering a Go to column
value that is greater than the width of the data page, you can remove the second
line by shifting the contents of the second line outside the data page.
