ToolBox "Type Mismatch"; Use VARPTR on Array Parameter (58820)

SUMMARY

Many of the ToolBox statement calls documented in Section E.10.3 (Pages 497-524) of "Microsoft QuickBASIC for Macintosh: Language Reference" incorrectly show passing arrays by simply passing the first element of the array.

In most of these cases, this causes the error "Type Mismatch" on the ToolBox statement. To avoid this error, pass the VARPTR of the first element of the array.

One exception to this rule is the return array for register-based calls. This array can be passed with the first element of the array without using VARPTR.

The following routines on Pages 497-524 should pass the VARPTR of the first array element: This information applies to Microsoft QuickBASIC Version 1.00 for the Apple Macintosh.

   DIM pattern%(3)
   pattern%(0)=&HAAAA
   pattern%(1)=&H5555
   pattern%(2)=&HAAAA
   pattern%(3)=&H5555
   ToolBox "i"
   ToolBox "P", &HA87C, VARPTR(pattern%(0))
