#include <Array.au3>
_ArrayColDelete ( ByRef $aArray, $iColumn [, $bConvert = False] )
| $aArray | Array to modify |
| $iColumn | Column to delete |
| $bConvert | [optional] If True then if only one column remains the array is converted to 1D |
| Success: | the number of columns remaining. |
| Failure: | -1 and sets the @error flag to non-zero. |
| @error: | 1 - $aArray is not an array 2 - $aArray is not a 2D array 3 - $iColumn is outside array bounds |
The function does NOT update any count element within the array, but the return value of the function (if successful) gives the final number of columns in the array.
