 TOPIC ---------------------------------------------

 Are there any Applesoft BASIC commands to invoke super-high-resolution
 graphics
 on an Apple IIGS?

 DISCUSSION ---------------------------------------------

 The super-high-resolution graphics of the Apple IIGS are not directly
 available from Applesoft.  Applesoft BASIC supports only the original Apple
 II low-resolution graphics (40x48 or 40x40 with 4 lines of text) and
 high-resolution graphics (280x192 or 280x160 with 4 lines of text).

 One solution is "Iconix IIGS" from So What Software.  This is a set of
 machine language subroutines accessible from Applesoft.  They provide an
 interface to the super-high-resolution graphics mode of the Apple IIGS.

 Other BASIC solutions for super-high-resolution graphics mode include
 Complete BASIC Compiler from Complete Technologies, AC/BASIC from Absoft
 Corporation, and Micol Advanced BASIC from Micol Systems.

 The Complete BASIC Compiler is similar to Apple's GSBASIC (available from
 APDA) with the addition of graphics support.  AC/BASIC is compatible with
 Microsoft's QuickBASIC language and provides graphics support similar to
 what is found in QuickBASIC for the Macintosh.  Micol Advanced BASIC is
 modeled after Applesoft.  Anyone familiar with Applesoft should be
 comfortable with Advanced BASIC.

 GSBASIC from APDA provides calls to QuickDraw II.  However, GSBASIC does
 not directly support graphics commands within the BASIC language syntax.
