Trying to start using G71 multi-repetitive cycle on Puma 8HC turning center.

This is simple code I am trying:

Code:
G20 G90 M17
G28 U0. W0. T0600 S600
M42
G50 S2000
G57

M03
(TURNING TOOL #6) 
G0 X2.2 Z.2 T0606
(TOOL CLEAR OF PART)
G96 G99

G71 P100 Q101 D.05 U.02 W.02 F.010
N100 X.5 Z0.0
X0.7 Z-.45
Z-.105
X1.25
G03 X1.75 Z-1.55 R.5
G01 Z-2.5
N101 X2.2
M05
M30
%
When the G71 line is executed I get alarm: "Illegal use of decimal point"

Can anyone tell me what I am doing wrong?

Cheers,
Steve E
