Best Practice for Library Building and Toolboxes
#9
Quote:@bplus -  5) Arrays should be hard indexed.  Don't DIM SHARED Array(10); instead DIM SHARED Array(0 To 10).  This prevents incompatibility if the user has OPTION BASE 1 in effect.
Wether that makes sense? If you declare an array with A( 0 To 10) you have eleven array elements, despite OptionBase 1.
To prevent this you have to fill the array with 1 to 10. With it a declaration with A(0 To 10) has no practical use.

Code: (Select All)

Option _Explicit

Option Base 1

Dim As Integer feld(0 To 10)
Dim As Integer feld2(0 To 10)
Dim As Integer feld3(10)

Dim As Integer a, b, c, d

Locate 3, 3
For a = 0 To 10
  feld(a) = a
  Print Using "## "; feld(a),
Next

Locate 5, 3
For b = 1 To 10
  feld2(b) = b
  Print Using "## "; feld2(b),
Next

Locate 7, 3
For c = 1 To 10
  feld3(c) = c
  Print Using "## "; feld3(c),
Next

'Error - Out of range.
Locate 9, 3
For d = 0 To 10
  feld3(d) = d
  Print Using "## "; feld3(d),
Next

End
