PACER-DATA ENTRY, RETRIEVAL, AND UPDATE FOR THE NATIONAL COAL RESOURCES DATA SYSTEM (PHASE I)

PACER is a set of programs, written in FORTRAN IV, which extends the capability of GRASP and which has been developed in response to the need for a computer-based National Coal Resources Data System (NDRDS). PACER allows the user to enter data into one of three files, to search for and retrieve records using specific data elements, and to modify and update existing data records. All coal resource records west of the Mississippi River are ground into WCOAL, whereas those east of the river are grouped into ECOAL. Each data record in WCOAL and ECOAL reflects a unique tonnage estimate of coal resource in a predefined category of thickness, overburden, and reliability of estimate. The USALYT file contains published coal analytical data and is structured to be as compatible as possible with the coal-resource tonnage files; however, it is not yet separated into east and west. A detailed description of the files is accompanied by user documentation for the use of the data files. A programmer's reference is also included to facilitate the installation and use of this software system on other computers.
