Subject:      numbering readmissions

hello--
here is some sample data:

id    admit    discharge
1     1/1/01   1/10/01
1     1/15/01  1/20/01
1     1/30/01  1/31/01

I would like to create a variable that denotes a "0" for the initial
admission (1/1/01) and then a "1" for the next admission, and the a "2" for
the next admission.  I'm really not certain how to do this properly.  Any
help, much appreciated.
