Adding prefix to all observations in column

[Thomas Zhang]

I have a column of identifiers which are e.g. :

58473J
50046Q
22631J

I would like to add a prefix in front of all these observations. How should I program this in stata?

[Rich Goldstein]

how about:

gen newvar="pre"+id

where I have assumed that id is the name of the current variable (not column) and the pre is the prefix you want to add; you will obviously need to change the name of the new variable, the name of the old variable and the substance of the prefix you want to add as appropriate; please read the FAQ before posting again (to make it easier for us to help you)

Thank you , I will do that. This thread could be closed
