st: Overlapping dates

[Anton econ <econaniv@yahoo.com>]

Dear Stata Useres;

I am facing the following problem. In my data set I
have a number of overlaping dates of 
start and end of variouse prorgammes. I would like to
create a dataset which would 
consists of consequtive dates and contain information
on types of programmes. 
(see exaplme below). 

Potentially this can be solved with the spellsplit
command which is a part of SPELLUTIL package.
However "spellsplit" allows only to sum or average
variables included into the dataset.
The "DISJOINT" ado does not seem to solve the problem
either.

I would very appreciate your advice!
