# pcb-rnd - the [dynstyle] patch

Pcb-rnd doesn't have a hardwired limit on number of routing styles anymore. Routing styles can be created on the fly and are saved to and loaded from .pcb files.

There's no theoretical maximum explicitly set either. An implicit maximum exists and is sizeof(int) - should be at least 2^31 on most systems.

## save/load and compatibility

The first 4 styles are loaded and preserved by mainline. Styles above 4 would probably be deleted in a mainline load-save cycle. The number 4 is a constant value that can be changed if mainline is recompiled.

## plans

GUI HID representation of styles (especially in menus) need more testing.
