<p><b>Return:</b><br>DS:SI buffer updated
if length byte is nonzero, the following bytes contain the uppercase
internal command to execute and the command line buffer contains the
command's parameters (the first DS:[SI] bytes are ignored)
</PRE>
<p><b>Notes:</b>
This call requests execution of the command which a previous call to
AX=AE00h indicated was resident.
APPEND hooks this call
<p><b>BUG:</b>
Novell DOS 7.0's COMMAND.COM (prior to Update 12) will attempt to run
a disk program with the indicated name even if the returned length
byte is zero, because the register used to flag this case is
clobbered without first checking it. The workaround is to set the
command name buffer to "REM" followed by enough blanks to pad out
the original command's length, which will also work with MS-DOS 6.
