Redirecting files: tips

Some redirection combinations present special problems due to the specific characteristics of the device. In particular:

• You should not redirect save files.
• You can redirect nonsequentially processed database files only to another database file or a DDM file.
• You can redirect Display files and ICF files that use multiple devices (MAXDEV or MAXPGMDEV > 1) only to a display file or ICF file.
• Redirecting a display file to any other file type, or another file type to a display file, requires that the program be recompiled with the override active if there are any input-only or output-only fields. This is necessary because the display file omits these fields from the record buffer in which it does not use them, but other file types do not.
