The Place Double-Size Line command creates a double-size line with a single command,
providing a simpler alternative to the Display Double-Size Line command for making a double-
size line.
When this command is processed, the text and attributes on the line occupied by the cursor are
duplicated on the line below. The line the cursor is on becomes the top half of a double-size line
while the line below the cursor becomes the bottom half of a double-size line. This command
makes a single normal size line both double-high and double-wide. For example, assume the
following lines are being displayed before the Place Double-Size Line command is received:
This is the line the cursor is on.
... this is the next line...
... and this is the third line.
When the host sends the Place Double-Size Line command, the TCS displays:
This is the line the cursor is on
...
... and this is the third line.
As with double-wide lines, the characters on the right half of a normal size line disappear when
the line is converted to double-size. The characters in the right half of both the top and bottom
lines reappear when the lines are restored to normal with the Display Normal Line command.
When a double-size line is placed, the cursor may move horizontally across the screen in order to
remain in the same character column position. If the line was originally a normal line and the
cursor was past the midpoint of the line, then the cursor is repositioned to the end of the double-
size line.
The Place Double-Size Line command never causes any scrolling. The region of the display
affected by this command is restricted to the scrolling region when Origin Mode is set. When this
command is issued, only the top half of the double-size line will be displayed if the cursor is at
the bottom of the screen (or of the scrolling region with Origin Mode set).
To change any characters in the double size line that this command has created, there are two
alternatives: the host can change the characters in the top line and then issue the command a
second time, or else change the characters in both the top and bottom halves of the double-size
line.
Any characters this command replicates retain their original NRC translation
(
if any).
