It wasn't a Stata program, as they didn't have Stata in the early-mid
1980s, at least at Sussex University (where I did the reading for my
DPhil at weekends) and at LSHTM (where I worked during the week and ran
the programs at odd moments). It was a Pascal program, used to input an
output file written by SAS and output an input file read by SAS. And it
was originally written on punched cards, which LSHTM didn't finally
phase out until 1986.

Roger: Thanks for changing that name. However, you lost out on any future competition for the most bizarre-looking Stata program name in history. It sounds like a long drink going down a very thirsty throat.

As it happens, the original ancestor of -somersd- was called -lllgglgg-,
and calculated output variables ll, lg, gl and gg, containing,
respectively, in each observation, the number of other observations with
a lesster X-value and a lesser Y-value, the number of observations with
a lesser X-value and a greater Y-value, the number of observations with
a greater X-value and a lesser Y-value, and the number of observations
with a greater X-value and a greater Y-value.
