- SD has always had a very obscure bug which is now fixed. In addition,
- SD-79A had a bug in the FENCE routine (a line read LDA ':' instead of
- MVI A,':'). The bugs are now fixed. Two versions of the COM file are
- provided, SD-80V.COM for vertical display, and SD-80H.COM for normal
- horizontal display. Do not mistake the V and the H in the filename
- for a version number modifier!

- The bug in SD-79A (and all previous versions of SD) was noticed by
- Gene Head who notified me and asked for a fix. The problem is that
- when SD found the last extent of a file and the EX field was 00, the
- S2 field was non-zero and the RC field was 80, SD dropped that
- extent in favor of the next lower one. The reason is that the internal sort
- routine sorted 12 characters (F1..F8, T1..T3 and EX) where it should
- have not included EX in the sort. The problem is only noticeable with files
- whose size is just larger than an even multiple of 512k (i.e. 520k, 1030k
- and so on). Obviously, only large files were affected.
