misunderstood, laughable or a disgrace?

re 4.128
check out the new function explanation in the manual
set_pullup(1,PIN_B1);
LOL
it ranks right up there with the consistent style of calling % "Modules"
instead of Modulus
really this new discovery tho - it is not so funny -
as an attempt to use it with 16F887 which has
pullups on port B
yields "undefined identifier"
the same happens if you use the goofy syntax
set_pulldown();
all the datasheets i have read call it pull up for a good reason - UP is the only direction you can pull the pin on port B
Neither of the offered syntax possibility
is recognized by YEE NEW compiler
i can get it done w/o this compiler "assistance" but
any enlightenment would be nice.

A few of the latest chips support individually programmable _pulldown's_ as well as pullup's. On these, 'up' is _not_ the only direction you can pull a pin.
These functions are only available on such chips.
