### FIND

Command FIND will search the input file according to some selection criteria, either specified as command options or set with the SET command. The current index will be ordered according to the sorting criteria, set with SET SORT command. Some options allows the input file to be updated before the search or to append the results to a previous current index. FIND will update the SIC variables FOUND that gives the number of observations found and CX_NUM[:], a list containing the observation numbers of the current index. These can be used in procedures, as is the case of the pipeline scripts.
