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 [;] Parameter path line Format clamped integer clamped integer Functional Range 0, 1, 2, or 3 0 or 1 Default 0 (horizontal) 0 (normal Line Feed) 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). 23-46 The Character Group EN
