I have uploaded XF.ARC to SIMTEL20.  It contains XF.C (in Turbo C and
assembler) and XF.COM.  It searches for a byte pattern specified in
hexadecimal in the files requested.  It will search files in sub-
directories recursively.  The actual searching is done in assembler to
utilize the processor's string search instructions.  Description:

XF.ARC          Find hexadecimal pattern in file tree fast

Thanks, Mark!  I appreciate your policy of including source code.
It's a great learning tool.  This utility will be good for searching
for viruses with known patterns.
