Header Array Files (HAR files)

Data for economic models (for example, input-output tables) are often held within GEMPACK on files called Header Array or HAR files. Header Array files contain one or more arrays each containing data values. An individual array of data on a Header Array file is accessed by supplying the unique 4-character identifier (or Header) for that array of values.

The data values held by an individual array can be either all real numbers, all integer numbers or all character strings. Depending on the type of data that is to be stored, the number of dimensions allowed varies.

Headers for arrays on any one file must be unique since the header acts as a label or primary key to identify the associated array.

You can learn more about HAR files from the ViewHAR online help.
