Sometimes you need to set all variables of an observation to blank, as you do when you are creating a blank dataset (in the LOG you will see at message coming up that variables are initialized). The following example creates a dataset with zero observations and uses the CALL MISSING routine to avoid the initialized variable message appearing:
7 data PopulationData2008; 8 attrib year length=8 label='Year' 9 population length=8 format=comma10. 10 label='Population Count'; 11 call missing(of _ALL_); 12 delete; 13 run;
NOTE: The data set WORK.POPULATIONDATA2008 has 0 observations and 2 variables.
