This may seem like a dumb situation, but I cannot find the information I am looking for and don't have the ability to experiment.
If I use G96 S220 for a facing operation, change out tools for a different operation but want to use the same SFM, can I write G96 without the S word?

Example (written for just this example, don't care much for grammar or form here):
G97M3S200
G50S4200
G0X2.02
G96S220Z0.
G1 X-.03 F45
G0Z.01
G97U20.W20.
M5
T050505
S200
G0X2.2Z-1.2
G96G1X1.8F22
....

What SFM would the G96 use? Would it take the S word used for G97 or the previous G96 word?
