is it possible to make such module to calculate MEAN and SEM automatically?

for example I create a table named table1

If I append wave1 to table1, a new wave contacting the mean or sem value of wave1 will be generated automatically.
If I were doing this, I would write a function that takes a wave as input. The function would:

1) append the wave to a specified table
2) compute mean and standard error
3) make a new wave for mean and standard error
4) append the new wave to the same table

The function can be invoked using WinName(0, 2) to append to the top table.

Another function could be made that uses Prompt and DoPrompt to give it a user interface.
