DV, Define Variable Text Path
This command specifies the text path for subsequent labels and the
direction of Line Feeds as either right, left, up, or down. Use DV to
“stack” characters in a column.
DV path[,line;]
or
DV [;]
The DV command determines the text path, the direction that the
current location moves after each character is drawn and the direction
that the Carriage Return point moves when a Line Feed is included in
the label string.
z No Parameter— Defaults the text path to horizontal (not stacked)
with normal Line Feed. Equivalent to (DV0,0).
z Path— Specifies the location of each character with respect to
the preceding character, relative to the labeling direction defined
by the DI or DR commands. The text path set by DV is not
affected by changes in P1 and P2.
• 0 — 0 degrees.(Right) Within a label, each character begins
to the right of the previous character. This is a horizontal text
path (unless altered by DI or DR).
• 1 — –90 degrees.(Down) Within a label, each character
begins below the previous character. This is a vertical text path
(unless altered by DI or DR).
• 2 — –180 degrees.(Left) Within a label, each character begins
to the left of the previous character. This is a horizontal text
path (unless altered by DI or DR).
