For each element of an ElementList: is there an index?

[nimic]

Hello

I want to repeatedly run a calculation over 2 channels of many groups, such as

ChnMapLinCalc("[i]/chan A","[i]/chan B,.... )"

and the like, which take 2 input channels

Now this could be done quite efficiently using lists, e.g.

Set oXList = data.getchannels("*/chan A")

Set oYList = data.getchannels("*/chan B")

and run

for each oXCh in oXlist

Set oYch = oYList( index of oCh in oXList )

       Call ChnMapLinCalc(oXCh, oYCh)

next

However, I cannot find a way to retrieve which index in oXList my loop is at.

(Apart from some workarounds with loop variables like i=0: i=i+1. in which case I could just as well discard the ElementList- elegance.

OTOH, there must be some type of internal pointer to the list element.

Thank you for suggestions.

You can just loop by index instead of using for each

Option Explicit

Dim oMyChns: Set oMyChns = Data.GetChannels("T*")
dim i : for i = 1 to oMyChns.Count
  LogFileWrite(oMyChns(i).name)
Next
