How to copy upper value to missing

[Max Jasper]

Hi all,
 
SPSS syntax question:
 
Variable V1 has missing values between case(m) and case(n):
What is the syntax for replacing missing values of V1 between case(m+1) to case(n-1) with its value at case(m)?
 
Many thanks,
Mike.

Hello Max,

with lag function you can copy the value of var between cases.
IF missing(V1) V1 = lag(V1,1).
EXEC.
