What’s the means of

PT, PCYL, PPOL
AX, AXYZ, AXZX, AXXY
AR, ARYZ, ARZX, ARXY
AXAX,AXAR

for REF item in SPT?

Relative coordinates/projection etc.
Read the manual, most of the explanatory text under spt is dedicated to this.

I create a parabola curve axis ‘RIBR’ as below:

GAX ID TYPE
‘RIBR’ AXIS
GAXA S X Y SX L
0 0 0 1 100
GAXH S H R
0 0
48 38.4 19.2
96 0

Now I want to create a SPT at S=48 (x=48,y=0,z=0) and project it onto the axis ‘RIBR’

I use

SPT NO X Y Z REF NREF
101 48 0 0 AX ‘RIBR’

But it doesn’t work
