-
- LUU duplicates the A(dd) and U(pdate) functions of LU.
- When used with LUT and LUE, original file dates are
- preserved and recorded.
-
- The advantages of LUU are:
-
- - smaller, so a copy can be kept on the "system" disk
- - faster, mucho
- - handles paths and wildcards
- - retains input file (or member) date/time
- - replaces in place (later)
-
- Examples:
- LUU a:AQM.LBR b:*.AQM
- LUU PCT366.LBR b:PCT366.*
- LUU c:\test\source.lbr b:ab??xx.*

- File Formats:
-
- An LBR file consists of a directory and one or more
- "members". The directory contains from 4 to 256 entries.
- Each entry is 32 bytes long and describes a member, if
- one exists.
-
- The first directory entry describes the directory
- itself. Thus, the number of entries allocated is increased
- by one.
-
- All space allocation is in terms of sectors. Each
- sector is 128 bytes long. Four directory entries fit
- in one sector, so the directory is allocated in multiples
- of four.
-
