photonblaster Posted February 12, 2021 Share Posted February 12, 2021 I am missing something here...I do not know why the second to last array assignment of this code snippet does not work Sorry if I am not using the correct "buzz" words to explain what I am intuitively expecting to be OK is not OK. Works of course-->: two arrays, same dimensions, different values, "A=B" works after the two arrays are declared and populated with Local statement . But "A=hard coded array" does not work even though "hard coded" array has same dimensions as the declared array and is the same as was assigned to array B in its declaration statement. As expected from searches, re-declaring the "A" array works to re-assign new array values, but it seems strange to me to have to redeclare an array when I just want to re-assign the values and not change its dimensions. Obviously not a burden to use "Local" again, but I do not see why this is needed. Worded differently.... IF Local ArrayA=an array of values Local ArrayB=an array of values Then Array A = B works if dimensions are the same. But A=[array of values of B in its declaration] does not work. I suspect, which is not clear in the help file for the arrays that I found, not only do you have to use Local/GLobal/Dim when you first declare an array, you must also use it whenever you want to re-assign values to an array other than with a variable (A=B). Of course you can also loop through the array using cell indices for all its cells, but this, to me is also cumbersome. #include <Array.au3> Local $aArray1D_Col[1][10] = [["AA", "BB", "CC",44,55,66,77,88,99,"JJ"]] _ArrayDisplay($aArray1D_Col) Local $aSecondArray1D_Col[1][10]=[["11", "22", "33",44,55,66,77,88,99,"TenthCOL"]] _ArrayDisplay( $aSecondArray1D_Col) $aArray1D_Col=$aSecondArray1D_Col ;works _ArrayDisplay($aArray1D_Col) ;Why does this assignment of values to the array not work? $aArray1D_Col=[["11", "22", "33",44,55,66,77,88,99,"JJ"]] ;But does if you re-initialize the array with LOCAL Local $aArray1D_Col[1][10]=[["11", "22", "33",44,55,66,77,88,99,"NEW TenthCOL"]] _ArrayDisplay($aArray1D_Col) Link to comment Share on other sites More sharing options...
jchd Posted February 12, 2021 Share Posted February 12, 2021 In AutoIt, array literals are only supported inside a declaration or redeclaration. For instance you can't write If $a = [1, 2, 3] Then ... Use Dim to redeclare a variable: this preserve its scope (local/global).

Especially the "hint" on using Dim for future assignments to literals so it preserves the original declared scope, not particularly obvious from the help files. Sorry about posting in wrong forum, I will try to do better. Link to comment Share on other sites More sharing options...
