How can I change the prompt-string from within a program?

I tried, using turbo-c's getenv("PROMPT"), which returns a pointer
to that place in the memory, where the prompt-string is stored
(which is okay).

But seemingly, DOS creates a copy of the environment table, and the
getenv returns a pointer to the copied env-table.
So, when the program ends, DOS gets its old env-table, and all changes
were futile. :(=

So, how to change the original environment table?

Any solutions welcome (c, mod2 or assembler, please).

Thanx in advance.
	Kai
