Yup - sorry 'bout that - my spell checker is obviously oriented towards
Shakespeare!

 >> There are a lot of machines still running that don't have the ability to
use %len.  Many more than you think. ......

While I agree that a certain degree of lowest common denominator is
essential - V4R2 is pretty old.  Are there really that many shops on
releases earlier than that that are doing serious development?  I certainly
don't come upon them - a few at V4R2 and V4R3 but nothing earlier.

Why not write the code to take advantage of the newer function and tell
people how to handle it _if_ they don't have the capability?  Most of my
teaching material is done that way and it seems to work well.  Also helps
people to understand that there is "good stuff" waiting for them if they get
a bit more up-to-date.  I think this is particularly true when teaching new
techniques.  Why teach new techniques using "old" tools - it doesn't make
sense.
