Is there anyone out there who can explain what's happening on my ][e?
Here's the contents of foo1.
800:20 8E FD JSR $FD8E {CROUT}
803:20 1B FD JSR $FD1B {KEYIN}
806:60 RTS
Here's the contents of foo2.
800:20 1B FD JSR $FD1B {KEYIN}
803:60 RTS
I've bsaved both files under 3.3 DOS (I think this could
be the cause of the problem) and I BRUN both programs (from applesoft).
The program foo2 returns to the "]" prompt after pressing a key while
foo1 just hangs there after I press a key.
Both programs returns when I call them from applesoft and monitor
(with CALL 2048 or 800G).
One last note-- on the screen the programs looks like this:
The "x" is the location where the prompt for the KEYIN appears:
]BRUN foo1
x
{And the program hangs}
]BRUN foo2x
]
{etc.}
PLEASE *MAIL* REPLIES TO ME.
This is in caps because the last time I said this some one went ahead
and posted their answer anyways. I think this sounds appropriate:
Chisholm's Third Law (a corollary): If you explain so clearly
that nobody can misunderstood, somebody will.
