Accessing Files Programmer's Guide: HP 3000 MPE/iX Computer Systems > Chapter 2 Creating A FileSummary of Overrides |

If a FILE command has been entered that contradicts some of the HPFOPEN/FOPEN parameters for a file, which takes precedence? What happens if some parameters are left out? The file system maintains a hierarchy of overrides for just such situations (illustrated in Figure 2-1 “File System Hierarchy of Overrides”): Since the physical characteristics of a file cannot be changed after it has been created, it makes sense that the file label would take precedence over all commands. Other determinants are effective only when a new file is being created.
