I'm getting older, I think I'm getting smarter too (maybe my wife has a different opinion :)), so I combined Surprises Part II and Part III together.
The example has multiple errors (misspellings, parenthesis issue) and I was thinking "Why can't they give a correct working example!!!!"
But then I was so lazy in correcting those and I tried (I thought I could raise a documentation bug) the same command and to my surprise it validated.
Then I thought if this one works, why not this @IDESCENDNATS. To my surprise (that was a big one) that worked too.
This was also a part of the above (@share) discussion and John Booth pointed out that Essbase only matches the first four characters of a function.
I experimented more on it and then figured out that what John said is partially true!!!!!
Essbase recognizes all functions with first 4 letters if the argument is a mbrname
So @CHILDNER works. Try it if you don't believe me.
I don't know how many of you got a hoax mail which claims that "Brain can read jumbled words if the first and last letters are not jumbled."
Now I can spread one which says "Essbase can read functions if first 4 letters are correct"
