I obtained data in this form:

354            1  16151.351    male  yes    2    no      no
354            2  16151.351    male  yes    2   yes      no
354            3  16151.351    male  yes    2     .       .
354            4  16151.351    male  yes    2     .       .
354            5  16151.351    male  yes    2     .       .
 
However, because this person only experienced 2 injuries, I wanted the 
data in this form:
respnum_  injnum   finalwt2  gender  ir1  ir2   ir3_  ir4_1_
354            1  16151.351    male  yes    2     no      no
354            2  16151.351    male  yes    2    yes      no
How can I keep the number of records for a given respondent equal to the 
number of injuries experienced?

Assuming that ir3_ and ir4_1_ are 0/1 numeric variables, no/yes being the 
value labels:
 
   drop if ir3==0 & ir4_1_==0
 
Hope this helps
