G4 Dwell parameters

[mmcp42]

What exactly do you need the dwell for as sometimes there are better ways of doing things.

Example, i have a 4 second delay after every toolchange where coolant needs to come on so allows the coolant to flow before the tool starts cutting.

well there are two answers:
a) I want to implement a gcode interpreter "properly" so I need to know what the G4 syntax means
b) I am using Eagle to lay out PCBs; the gcode converter spits out a (G4 P3) delay after starting the spindle
clearly that needs to be 3 seconds not 3 mSeconds!

make sense?
