It's perhaps a COMMAND.COM issue.

I cannot remember all details currently, but since the cmdline in the PSP is restricted to 126 bytes, MS has extended this in MS-DOS 7.x : there's supposed to exist an environment variable CMDLINE, which may hold a cmdline of "any" size. HX's Win32 kernel emulation dkrnl32 uses this environment variable if possible.

MS-DOS forever!
