Update allows you to specify portions of a series, or list of series whose observations you wish to modify. It is for interactive use only.
UPDATE <list of series> ;
Usage
UPDATE is a special form of the ENTER command. The only difference is that UPDATE is expecting to modify an existing series. You will be prompted to specify the observations you wish to update -- your response must conform to the rules for specifying a SMPL. A single number will be interpreted as a request to update a single observation. Prompting and storage will be defined by the SMPL you specify, and the most recent FREQ prior to the UPDATE command. If the frequency is not appropriate for the series, you will encounter errors.
In response to the prompt for data, you may enter as many items per line as you like -- the prompts will adjust accordingly. Prompting will cease when the observations you specified have been updated, and the series will be re-stored. If more than one series is being updated, you will be prompted to update them sequentially.
