easy way to delete a multi-dim'ed array row

_arraydelete() is bombing when I try to delete a row in my multi-dim'ed array

for $i = $aSource[0][0] to 1 step -1
    if $aSource[$i][3]/1024/1024 < $iMin then _ArrayDelete($aSource, $i)
Next

I'm assuming then that _arraydelete() only works on single-dim'ed arrays.

If that is true, is there an easy way to delete a row out of a multi-dim'ed array?

TIA

No.

But here's the hard way:

#Include<Array.au3>

; Demo _ArrayDeleteEx() with a 5D array
Dim $avMultiD[3][4][5][6][7]
$avMultiD[1][2][2][2][2] = "Test cell stored at $avMultiD[1][2][2][2][2]"
$avMultiD[2][2][2][2][2] = "Test cell stored at $avMultiD[2][2][2][2][2]"
MsgBox(64, "Debug: Before", "$avMultiD[1][2][2][2][2] = " & $avMultiD[1][2][2][2][2])
_ArrayDeleteEx($avMultiD, 1)
MsgBox(64, "Debug: After", "$avMultiD[1][2][2][2][2] = " & $avMultiD[1][2][2][2][2])

Damn....

Guess I'll just create another array and fill it while I loop through the original array then blow the original away

Oh well.

I looked over the _ArrayDelete function...all it does is create another array too,

Suggestion to AutoIT dev team: how about a true entry remove from an array....with options to renumber array and update array[0] count. Should work with all arrays, single and multi-dimed. :rolleyes:
