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.
