It surely would be easier to use genr y = ceiling(x)
Agreed.

Also, when we are discussing new functions, a "rank()" function for the
"genr" command, that gives the ranks of the values in a vector, with ties
resulting in ranks being averaged, would be useful.
Doh!
I realise now that you want the mode, not the corresponding observation.
How stupid of me. Sorry.
Yes, both the mode() function and the rank() function are very much
doable. Allin and I will meet next week and we'll see to it.
