Re: A85: Shell usage
Re: A85: Shell usage
You're talking about the reason I wrote MISh. It is the smallest shell to
exist right now that is ZShell compatible, and there is only one program
I've ever seen that doesn't run under it. Its on ticalc if you want it.
-> I apologize, I wasn't thinking perfectly. Of course, it's no trouble for
-> people to get new shells if someone else has them. There are a few
-> problems, however:
-> * In general the multiple shells are not compatible with each other, so
-> no one can have shell-specific programs for more than one shell at one
-> * Furthermore, all the shells can only be transferred through a memory
-> backup, so when you get a new shell from someone you lose even the
-> shell-independent (i.e. ZShell) programs you had unless the other calc
-> has room or you have a third calc to store them on or a link or
-> * And there is the disadvantage I mentioned that the more advanced
-> shells take up more space.
-> Of course, I'm not disagreeing that it sure would be nice if there were
-> a "standard" shell that everyone could write for and use. But given the
-> current state of the shell...um...I want to say "market", but they're

-> only an advanced shell provides.
