st: Different records per patient

["Ziad El-Khatib" <ziad.khatib@gmail.com>]

Dear subscribers,
I have dataset in STATA format, where we met patients at 6 time
points. I want to:
 - make new variable to define each time point as visit1, visit 2, visit 3
(some patients were met 3 times, some 6 times...)

 - so i can select patients per visit etc..


Any tips?

Thank you and best regards
ziad
