I cannot see a question so far. If you want to extract the day from your
strings:
*************
clear
input str18 date
20jan2007
16June06
06sept1985
21june04
4july90
9jan1999
6aug99
19august2003
end
gen int day=day(date(date, "DMY", 2010))
li, noo

thanks very much for your help!
I've another question about mata. I'm working with the regexm() function
in mata.
My question is the following code. Try directly the code...
clear
input str18 date
20jan2007
16June06
06sept1985
21june04
4july90
9jan1999
6aug99
19august2003
end
*** -regexs()- function works perfectly with stata
gen day = regexs(0) if regexm(date, "^[0-9]+")
list day
tomata
capture mata: mata drop example()
mata
real matrix example(var)
{
/// -regexm()- function seems to work with vectors
one = regexm(var, "^[0-9]+")
one
two = J(8, 1, "")
