Parameters

Example
// Simple subroutine that uses Primitive.get() to ensure
// that an optional parameter has a value
public fac(Number fac) // calculate fac!
// force (non zero) integer value
set fac = fac.get(1)\ 1
if fac < 0 quit -$$fac(-fac) // arbitrarily
if fac < 1 quit 1 // 0! and 1! both 1
quit fac * $$fac(fac-1) // use recursion
if fac < 1 quit 1 // 0! and 1! both 1
quit fac * $$fac(fac-1) // use recursion
