I can think of dumb ways to do this. Put

the differences and look at the summary
statistics using -summarize-.

Alternatively do it directly. This
code (1) assumes an ordered numlist,
minimum first (2) is not tested much.

tokenize "`numlist'"
local nn : word count `numlist'
local max = 0
local min = .
forval i = 2/`nn' {
        local j = `i' - 1
        local diff = ``i'' - ``j''
        local min = min(`diff',`min')
        local max = max(`diff',`max')
di "`min' `max'"
Many thanks Prof Cox, particularly for your "direct" advice.
Actually I thought that a simpler solution would be possible.

Anyway it looks effective. I will adopt it.
Thanks again.
