Alas, even 511 characters is too few, e.g. for compilation and link
commands.  And that is even before we consider this gotcha:

I'm not sure you can rely on DOS programs to support CMDLINE.  DJGPP,
for example, supports it only in the development sources (and in beta
releases of v2.04), so DJGPP programs compiled with official versions
of the C library will generally not work under 4DOS.

No, there's no pointer, but the command tail in the PSP should be in
special format to indicate that CMDLINE is to be used.
