Remarks
AEvalA() is similar to AEval() in that they both evaluate a code block once for each element of an array,
passing the element value as an argument.
The difference is that while AEval() ignores the return value of the code block,
AEvalA() assigns the return value to the array element.
See AEval() for details.
Examples
This example uses AEvalA() to create an array of file names in lowercase:
1FUNCTION Start()
2 LOCAL aFiles := Directory("*.dbf")
3 LOCAL nTotal AS SHORTINT
4 AEvalA(aFiles,{|aDBFFile| LOWER(PadR(aDBFFile[F_NAME], 10))})
