Line 1,010:
If one wants to create a new array consisting of transformed values then procedure mapdata may be more convenient.
 
=={{header|PowerShellPureBasic}}==
<lang PureBasic>Procedure Cube(Array param.i(1))
This can be done in PowerShell with the <code>ForEach-Object</code> cmdlet which applies a scriptblock to each element of an array:
Protected n.i
<lang powershell>1..5 | ForEach-Object { $_ * $_ }</lang>
For n = 0 To ArraySize(param())
To recreate a ''map'' function, found in other languages the same method applies:
Debug Str(param(n)) + "^3 = " + Str(param(n) * param(n) * param(n))
<lang powershell>function map ([array] $a, [scriptblock] $s) {
Next
$a | ForEach-Object $s
EndProcedure
}</lang>
 
Dim AnArray.i(4)
 
For n = 0 To ArraySize(AnArray())
AnArray(n) = Random(99)
Next
 
Cube(AnArray()) </lang>
