Passing variables to Word Functions

[Mauried]

Im trying to do something like this.

Function ReadSolar as word (optional smoothing as byte=10)  
var0=0
For x1=1 to smoothing
var0=var0+ Readad10(an0)
wait 10 ms
next x1
Readsolar=var0/smoothing
end function

The idea is to be able to take a number of readings from the AD converter
and average them a number of times, with 10 being the default.
The Compiler complains about the line with the function declaration in it.
If I leave out the as word define , it then compiles ok, but I then cant use the AD in 10 bit mode.
If I leave out the (optional smoothing as byte=10) and include the as word define it compiles OK also.
Anyone see what Im doing wrong.
Thanks

Try changing

Function ReadSolar as word (optional smoothing as byte=10)

to

Function ReadSolar (optional smoothing as byte=10) as word

From memory GCBASIC always requires the type to be after the parameters.

Thanks Hugh.
That worked fine.
Should have tried more variations,but its sometimes hard to guess them all.
