You can pass an array as parameter (by reference)

DIMENSION mar[3]
mar[1] = 1
mar[2] = 2
mar[3] = 3

avg=calcAverage(@mar)

function calcAverage(taMar)
EXTERNAL ARRAY taMar
local n,v,i
n=ALEN(taMar)
v = 0
for i=1 to n
  v=v + tamar(i)
next
return v/n

>Can anyone suggest a way to pass a variable number of parameters to a method or function where the maximum number is not known in advance?

>E.g. Foxpro pseudocode below:

>function calcAverage()
>local n,v,i
>n=pcount()
>for i=1 to n
> v=v+parameter(i)
>next
>return v/n

>I know that you can declare a maximum number of parameters. But what if I dont know in advance? Should I declare 10 parameters and do the following
