LB - Character plot
LB [ cs ] < terminator > [;]
cs : character string
 Plots character strings, numerical expressions, variables etc.
 Plotting is performed whether the pen is up or down.
 After plotting, the cursor moves to the position of the next character.

DI - Absolute direction
DI [ run, rise ] [;]
run : X direction component
rise : Y direction component
 Specifies the character plot direction.
 Values for the run and rise are clamped real numbers.
 The instruction is ignored when the values for both run and rise are 0.
 When the parameter field is omitted, the default value (horizontal direction) is used.
