SCRXY

                                   SCRXY
                                   =====

Get screen dimensions directly from screen driver - without use of
a channel!

        SCRXY limX%, limY%

Where limX% / limY% are return parameters only

Parameter errors trigger the standard error reponse.


Note:
-----

If the Pointer Interface (PI) is not present the "standard" values, ie
512 and 256, are returned instead. Clearly, this wont be correct if you
have a 768x512 screen size and no PI! This, however, appears to be how
TK2's SDUMP does things, so Im happy with that.

I added the standalone version of SCRXY (the relevant files have an 'i'
appended) to the mix as Martin Head has commented my code so well :o)

It is slightly more compact as it doesnt use any of my external libraries.
However, if SCRXY is to be part of a larger toolkit that also uses those
libraries, then it is better to use the non-i version.
