i have a subroutine that looks things up from the nab. the returned variable could either be a scalar value or an array. so my question is if i pass an argument to a sub with an dynamic array reference:
subName (rtrnVal())
is there anything i have to do in the main prog to account for a different return type?
thanks
Subject: re: passing/returning scalar v arrays
if I get you right you’re trying to pass an argument into a subroutine ByReference, change its value within the routine and then grab the changed value once you’re back in the calling routine (if I didn’t get you right then please forget the rest of this…)
I’d change two things:
use a function instead of a sub: functions are truly designed to return values
functions can’t return arrays, but they can return variants, and variants can be anything (including arrays)
So I’d do something like
function fncSomething(args) as variant
the calling routine would then query the function’s return value for its type, e.g. using something like
if isarray(fncSomething) then
…
Hope this helps
Subject: never used functions
been programming in notes since R1. another developer friend of mine recommended functions too.
i guess i gotta go figure them out now.
Subject: functions…
yep, think you should 
it’s easy: they’re the same as subs only that they can return something. The return value is assigned inside the function in that way:
functionName = returnValue
The function’s return type must match the data type of the return value. If the function returns an object you must use “Set functionName = …”
That’s all there is.
Good luck
Subject: notesdocument.getitemvalue always returns an array
notesdocument.getitemvalue always returns an array.
Dim total As Integer
Dim money As Variant
total = 0
money = notesdocument.getitemvalue( “quarterlyRevenue” )
Forall m In money
total = total + m
End Forall
