Why do you think so ?   AFAIKS the *pointer* field doesn't care how long the 
pointed-to string is ...

Add a "give me a pointer to the extended command-tail string" for the called 
program (the PSP can only hold 126 chars so it needs to be stored somewhere 
else) and it should be enough - if it fails than there is no support.  It 
can be used by the caller, to determine if it should apply the CMDLINE 
environment variable hack, as well as by the callee, for the same reason.

As long as you're busy upgrading stuff, do consider changing 2109 to a 
zero-terminated string too.
