ANSYS FSI modeling

Hello, I'm not sure my question is 100% relevant to this newsgroup, but maybe someone here familiar with ansys can provide some assistance. I'm trying to figure out how to do FSI modeling in ANSYS6.1 (which is the version currently available at my university), and my starting point has been the example given in the help file (see here:

What I cannot figure out is the logic behind this snippet of code:

MAXDISP = 0.85

*DEL,_FNCNAME *DEL,_FNCMTID *DEL,_FNC_C1 *DEL,_FNC_C2 *SET,_FNCNAME,'uxdsp' *DIM,_FNC_C1,,1 *DIM,_FNC_C2,,1 *SET,_FNC_C1(1),MAXDISP *SET,_FNC_C2(1),2.5 ! /INPUT,time.func *DIM,%_FNCNAME%,TABLE,6,4,1 ! Begin of equation: a*sin(omega*{TIME}) %_FNCNAME%(0,0,1)= 0.0, -999 %_FNCNAME%(2,0,1)= 0.0 %_FNCNAME%(3,0,1)= %_FNC_C1(1)% %_FNCNAME%(4,0,1)= %_FNC_C2(1)% %_FNCNAME%(5,0,1)= 0.0 %_FNCNAME%(6,0,1)= 0.0 %_FNCNAME%(0,1,1)= 1.0, -1, 0, 1, 18, 3, 1 %_FNCNAME%(0,2,1)= 0.0, -1, 9, 1, -1, 0, 0 %_FNCNAME%(0,3,1)= 0, -2, 0, 1, 17, 3, -1 %_FNCNAME%(0,4,1)= 0.0, 99, 0, 1, -2, 0, 0 ! End of equation: a*sin(omega*{TIME}) !-->

How is that array/table modeling a sinusoidal function? I can't see any pattern at all, let alone a sinusoidal one! Any help would be very much appreciated. Thanks.
