[Coco] (D)ECB and command-line arguments

[Arthur Flexser]

Well, since you are going to have to first load in some ML code, and have
it evaluate arguments when executed....

It would be essentially no more difficult to just hijack one of Basic's
existing commands (on a CoCo 3, where everything is in RAM).  Take a
command that is unlikely to be needed at the same time your routine is, and
just overlay it with your argument evaluation and other needed code.  You
could also overlay the name of the command with your name of choice that
has the same number of letters as the original name.   So all you need is:

LOADM"GORPCMD"               (no need for an EXEC)
GORP 5,28,"Hi there, I am the Gorp command"

(If your code exceeds the original command code in length, you have it
branch someplace else where it won't conflict with anything.)
