Lotusscript version of @Elements

This may be a dumb question, sorry :)

Is there a Lotusscript version of @Elements? I know I can loop through or even use UBound however curious if there is a better way now that we are on V12.

Thanks in advance

Hello

If you want to find the number of elements in an array, you can use the UBound function as you said.

Is there anything that Ubound cannot achieve for you?

With V12 also found the same UBound function for deciding the upper bound of an array.

Believe no new function in V12. Refer below doc

UBound Function

Hi there,

what are you lokking for ? What do you expect to find in V12?

If you use a non standard array that, for what ever reason, starts not with 0

i.e. DIM MyTestArray(-10 to 123)

you could define

Function Elements(TheArray)
     Elements=ubound(TheArray)-lbound(TheArray)
End function

Or even write a version for more that one dimension.

Sincerly

You're right Jochen from fast to slow:

1/ lbound/ubound

2/ evaluate("@element) => not sure it is fast but well....

3/ array loop

The only advantage in the not so faster loop (step 3/) is that I've changed the function call to pass a filter (to count number of elts starting with or containing a specific value)

Function Elements(anArray as Variant) as Integer
Dim i as Integer

i = 0
if isarray(anArray) then
Forall values in anArray
i = i + 1
End Forall

end if 
Elements = i
End Function

You can use such a code in LS:

Jerome,

that could become quiet an expensive operation for big arrays.
Ubound and Lbound are much faster.

Kind Regards

I guess evaluate in lotus script should do the job

Dim answer as variant

Expression$="@Elements(yourfieldname)"

Dim doc as notes document

*Set the document doc

Answer=Evaluate(Expression$,doc)

Thank you for all the responses. I was hoping they had an @Elements version via Lotusscript in V12.

Ubound can show 1 if the array is (0) and (1). The array should be 2.

Anyway, thank you for all the responses.
