No, unfortunately, PDS also capitalizes COMMAND$.  You can retrieve the
command line, case preserved, with the following:

========================== Begin CMDLINE.BAS ===========================



'* FUNCTION CmdLine$
'*    Uses DOS ISR 21H, Function 51H (Get PSP Address) to return the
'*    command line unmodified.  COMMAND$ is capitalized by BASIC, hence
'*    this function.
'*    QBX.LIB
'*    -------
'*    SUB Interrupt (IntNum%, IRegs AS RegType, ORegs AS RegType)
   DIM IRegs AS RegType, ORegs AS RegType = &H5100
   Interrupt &H21, IRegs, ORegs
   PSP% = ORegs.bx                           'Segment returned in BX
   Offset% = &H80                            'Offset% of command line

   DEF SEG = PSP%                            'Access PSP segment
   CmdLen% = PEEK(Offset%)                   'Get command line length
   Cmd$ = SPACE$(CmdLen%)                    'Read parameters....

   FOR I% = 1 TO CmdLen%
      MID$(Cmd$, I%, 1) = CHR$(PEEK(Offset% + I%))
   NEXT I%

   DEF SEG                                   'Restore DGROUP

   CmdLine$ = RTRIM$(Cmd$)                   'Return value
   Cmd$ = ""
=========================== End CMDLINE.BAS ============================
