How to append to a list in Automation Anywhere 10.5?

The list starts empty. Then I want to append an value to it for each iteration in a loop if certain condition is met. I don't see append option in Variable Operation.

I used lime's answer as a reference (thanks lime!) to populate a list variable from some data in an Excel spreadsheet.

Here's my automation for it:

Throwing in my 2 cents as well - my-list-variable appears to be the only mutable in size list you can work with. From my experience with 10.7, it only grows though.

So if you made a list with 60 values, and you wanted to use my-list-variable again for 55, you'll need to clear out those remaining 5 values and create an if condition when looping over the list to ensure the values are not whatever you set those 5 values to be.

Lists are buggy in Automation Anywhere and have been buggy for several versions. I suggest not using them and instead use XML.

It it a much more versatile approach and allows you to do much more that with lists. You can search, filter, insert, delete etc.

For the example you mention, you would use the "Insert Node" command.

You can use string split for this, assuming you know of a delimiter that won't ever be in your list of values. I've used a semi-colon, and $local_joinedList$ starts off empty.

If (certain condition is met)
    Variable Operation: $local_joinedList$;$local_newValue$ To $local_joinedList$
End If
String Operation: Split "$local_joinedList$" with delimiter ";" and assign output to $my-list-variable$

This overwrites $my-list-variable$.

If you need to append to an existing list, you can do it the same way by using String Join first, append your values to the string, then split it again afterward.

String Operation: Join elements of "$my-list-variable$" by delimiter ";" and assign output to $local_joinedList$
