Functions rock.
They fit happily as I-types subs() too.
SUBR('addThese',SUB.TOTAL,TAX)
One weirdism is that if you have internal subroutines you need to use
return(x) syntax. I usually use return(@null) to indicate that it's not
used.
function addThese(a,b)
gosub MySub:
return(ans)
MySub:
ans = a + b
return(@null)
The:end
per-functionally,

parameter list.
You can still pass other values back through the parameter list like you do
with CALLed subroutines.
I use it for if foo() then ... else...
Eg: if OpenFile(DICT,FILENAME,FILEHANDLE) then
