AX = AE01h DX = magic value FFFFh CH = 00h CL = length of command name (4DOS v4.0) DS:BX -> command line buffer (see #02977) DS:SI -> command name buffer (see #02978)
Return:
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)
Notes: This call requests execution of the command which a previous call to AX=AE00h indicated was resident. APPEND hooks this call
BUG: 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. (from padgett@tccslr.dnet.mmc.com)
