Deleting a category

[MD ROKIBUL HASAN]

Hi
I have 5 categories of a variable (education). I want to delete one category 'don't know'. Can anybody help me with the command here?

not sure what you mean by "delete" and not sure whether your variable is numeric with labels or is a string variable; if you mean deleting the observation with "don't know" on the education variable, I recommend against that; instead, just make the value be missing; assuming this is a string variable (please read the FAQ and follow its advice), you might try:

replace education="" if education=="don't know"
