Correction for FillArc ToolBox Example on Page 511 "Reference" (58821)

SUMMARY

The FillArc ToolBox example on Page 511 of the "Microsoft QuickBASIC for Apple Macintosh: Language Reference" is incorrect. The ToolBox statement does not use the rectangle parameter (r%()), and the example references the pattern parameter incorrectly (pat%()).

This information applies to Microsoft QuickBASIC Version 1.00 for the Apple Macintosh.

MORE INFORMATION

The incorrect example on Page 511 is as follows:

   TrapNo%=&HA8C2
   Toolbox "P", TrapNo%, (startAngle%), (arcAngle%), pat%

It should read as follows (note: the underscore is for display purposes only; VARPTR(pat%(0)) should be on the same line as the ToolBox statement):

   TrapNo%=&HA8C2
   Toolbox "P", TrapNo%, VARPTR(r%(0)), (startAngle%), (arcAngle%),_
                         VARPTR(pat%(0))

The following is a complete example using the FillArc ToolBox call:

   ToolBox "i"                  'Initialize toolbox and variables
   DIM r%(3), pat%(3)
   SetRect r%(0),10,10,100,100
   pat%(0) = &H5555             'Make checker pattern
   pat%(1) = &HAAAA
   pat%(2) = &H5555
   pat%(3) = &HAAAA
   startAngle% = 10
   arcAngle%   = 90
   TrapNo%=&HA8C2
   Toolbox "P", TrapNo%, VARPTR(r%(0)), (startAngle%), (arcAngle%),_
                         VARPTR(pat%(0))  'Should be on Toolbox line
