FNy #
Return the value of the current MOdel function at location #.

Example: 

PLT> MOdel LINR CONS ! Define a straight line
  1, LI: VAL( 1.00), SIG( 0.00 ), PLO( 0.00), PHI( 0.00)?
2.                   ! Set slope of line equal to 2
  2, CO: VAL( 1.00), SIG( 0.00 ), PLO( 0.00), PHI( 0.00)?
3.                   ! Set intercept of line equal to 3
PLT> FNY 3           ! Evaluate function at x=3.0
12.0                 ! The result
