Yes, both are fine, and Emacs is a whole world unto itself (largely
unexplored by me), for those wanting to branch off in this direction
(I look at the computer world as full of branch points -- people do
"random walks" and end up traversing entirely different pathways,
meeting up from time to time).

Great to share these amusements! In my world, it's all about
showing how computers have their distinct advantages over calculators
-- one of which is this ability to work with strings.
Calculators completely dominate in math curricula in my neck of
the woods, and teachers endless debate about their merits -- but
without seriously considering the computer as an alternative.
Here's some text from an article I had published in FoxPro Advisor
(an Xbase mag) in March of last year:
I live in Greater Portland, the Silicon Forest. Intel, Tektronics,
Hewlett-Packard, and Symantec all nest in this area, and Microsoft,
near Seattle, isn't far away.
The high tech sector is now Oregon's biggest employer. Oregon is
like an oil-rich state on the Persian Gulf, except our wealth,
being know-how, is more invisible -- and more renewable.
I bring up matters economic to give some background as to why
a "math makeover" might be taking hold here of necessity.
Our employers need computer literate, fast learners who aren't
math phobic. But then, what is mathematics exactly? Judging
from your average textbook, it's pretty much what we remember
from our own K-12 careers (arithmetic, geometry, algebra, and
calculus). But open a VFP manual and you see operators like
DTOT(), ASORT() and PACK. More than just number crunching or
even algebraic manipulation, our business world needs full-
fledged symbolic processing.
Business rules pertain to alphanumeric, not just numeric content,
and our character sets are becoming increasingly international.
Nor is it just businesses that need large data tables, relational
structures, and class hierarchies. Scientists and engineers
work with the same tools. So why postpone much significant
exposure to all of this content until college? Why aren't we
teaching VRML, XML and SQL in eighth grade? Certainly many
students are ravenous to learn this stuff, but when do their
teachers have the time to learn it all themselves?

Yeah, I goofed. Guido has linked the above directly from the edu-sig
page at python.org. His link goes to:
