(Type: Boolean, Default: FALSE)

<$.DUMP option>

── $.DUMP ─────────────────────────────────────────────────────────────┤

If $.DUMP is TRUE, and the first fatal error occurs in patch N (N > 1), the PATCH utility merges the first n–1 patches and locks them on a disk file. If the PATCH utility file had the title X/Y/Z, then this file has the title DUMP/X/Y/Z. The $.DISK option can then be used to restart the merge operation without rereading the first n–1 patches.
