Dear Statalisters,

I have a huge dataset and I would like to get rid of some observations
when opening it.
I want to open my dataset only if the first character corresponds to
'I' or 'J'
for the string variable 'diagp', I have something like:

diagp
I236
I256
I52
J46
J856
H343
etc..

I tried:
    use 'dataset.dta' if diagp=="[I-J]*"

But I am doing something wrong and I can't figurate it out.
Thanks for your help

Emma
