FILEINFO: Object file for utility.

User Instructions

The FILEINFO utility accumulates data on all of the files in a library, producing a data file. Information in this file includes the modification and ownership history, number of blocks used and allocated, file type, record size, and extents. This data file can then be used for disk space analysis or other management purposes.

The utility prompts for the library to be searched and the volume where it resides. It then requests the location of the data file to be produced. When all of this information has been entered, the library is processed and FILEINFO ends.

The completed file may be then be processed by a user program, the Wang File Management utilities (REPORT, DATENTRY, or INQUIRY), or any other means. A Wang control file is required for use with the File Management utilities; this is not supplied and must be constructed by the user. Press PF(14) at the INPUT screen to see a description of the fields in the file.

Programmer Instructions

All major screens in FILEINFO are GETPARMs, and it may easily be controlled from a procedure.

VOLUME      Press (RETURN) to continue or PF(14) for file
            structure documentation.

  LIBRARY   [outlib]    be created.
  VOLUME    [outvol]

Example of use

Easily used as a small-scale disk management utility. Can be run under procedure control, extracting information about specific libraries. This information can be analyzed, and files reorganized or deleted manually.

For example, here's how FILEINFO might be used to detect and report on files in more than three extents:

• Write a procedure to extract file information from production data libraries on the system.

• Use INQUIRY or REPORT to select records where the number of extents is greater than three.

Comments

Produces an 80-character consecutive file with most data required for disk management. Limited field size in record count (six characters) limits effectiveness for large files.
