To read efficiently the direct access statement: DEFINE FILE, READ, WRITE, FIND; supplied by FORTRAN 77, the user needs to keep memory of where each record is located in the file. Therefore, to update the file or simply to retrieve the information may be a hard job for different users. In the package, presented here, the file is subdivided into logical elements which are randomly accessed by means of a table of contents, recorded in the same file. Each element is supposed to be built up with records that will be processed sequentially or will have a structure of linked chains. Storing or retrieving the information from an element all one needs to know is its name. Some slight modifications are unavoidable for an efficient use on files with very small capacities (less about 10000 records).

Abstract
To read efficiently the direct access statement: DEFINE FILE, READ, WRITE, FIND; supplied by FORTRAN 77, the user needs to keep memory of where each record is located in the file. Therefore, to update the file or simply to retrieve the information may be a hard job for different users. In the package, presented here, the file is subdivided into logical elements which are randomly accessed by means of a table of contents, recorded in the same file. Each element is supposed to be built up with records that will be processed sequentially or will have a structure of linked chains. Storing or retrieving the information from an element all one needs to know is its name. Some slight modifications are unavoidable for an efficient use on files with very small capacities (less about 10000 records).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
