st: Replacing the missing observations

Dear All,

group	time	ewportret	ewdiffret

0	2007m4	.041679	             .
1	2007m4	.0375245	-.0041545
0	2007m5	.0449738	     .
1	2007m5	.0397919	-.0051819
0	2007m6	-.0240277	     .
1	2007m6	-.0188678	.0051599

The variable ewdiffret is the difference in ewportret between group 1 and 
group 0 for each time variable (thanks to Dr. Cox for the help with this). My 
question is how can i now replace all empty cells under the ewdiffret in the 
same month with the single ewdiffret value in that given month. Indeed i have 
too many empty cells in a given month and i want to replace them all with the 
single ewdiffret i have for that month.

For example: I would like to have the first empty cell under ewdiffret equal 
to -.0041545 as the time variable for both is 2007m4 and the second 
empty cell equal to -.0051819 as their time variable is 2007m5. Using too 
many replace functions takes a long time and may cause transcription errors.

Thank you,
