### GreEscape DEVESC_BREAK_EXTRA - Syntax

Simulation support:

This function is mandatory for hardcopy drivers, but may simply return a DEVESC_NOTIMPLEMENTED code. For other drivers, it is simulated by a handling routine in the graphics engine.

Description:

GreEscape DEVESC_BREAK_EXTRA changes the width of the break character on a hardcopy device. The handling routine sets or resets, as determined by the value of cInCount, an extra width value for the break character. Upon completion, the width of the break character is the default width specified by the font plus any extra widths set by DEVESC_BREAK_EXTRA and DEVESC_CHAR _EXTRA. The extra widths can be positive, zero, or negative.

Note: This escape code is implemented by old hardcopy drivers. The function of this escape code is replaced by the character attribute fxBreakExtra. See Character Attributes.
