sVr2 VAX SDB(1) help needed

[ams at hou4b.UUCP]

	I have an application in which some functions execute on a
malloc()'d stack.  Naturally, sdb(1) does not know where to find
local variables and parameters for these functions.  Is there any
way to tell sdb "no, don't look at the stack for main(), the stack
is really over here, at address xxxxx"?
	I can have the application print out the address and size
of the allocated stack, so I thought that diddling the maps with
the M command might do the trick, but I can't figure out how to do
this.  Can anybody help me?

	Thanks,
