Default Window Size

[stephan.zimmer]

Hallo all,

is there any way to set the default window size of emacs in .emacs?
I.e. to achieve the same effect as starting with --geometry=width x
height? If not, is there any workaround for that, i.e., placing some
default command line options in an environment variable?

For a given window, is there any way to locally restrict the width to
a certain value? I.e., say the window has width 200, but in a certain
buffer I don't want to exceed the 80 signs limit.

Thanks a lot. Best,

Stephan
