Hi! I'm trying to do some research with a professor and I've been tasked with learning SAS. I'm trying to use the proc sort command to sort some of the data and would like some help doing this: 1) Sorting data between years, i.e. from 1985-2005 2) Sorting data so it filters out/eliminates data with a certain character in the first slot of a cell. I.e., for SIC codes, I want to filter out any that start with 6 (6123, 6149, etc) 3) I want to add a column that shows how many firms are in a SIC 1-digit code. For example, I want to count the firms that start with 5 (5124, 5655), then sort them by Year. So an example would look like this: 1) A 5100 2 2) B 5101 2 3) C 4231 1 Thank you! If anyone can help me find some beginner tutorials/videos too, that would be great.
