Returning an array from a procedure

Is there a way to have a procedure return an entire array?

No, you must pass the array as a parameter, and then let the procedure fill it in.

Can anyone provide a simple example?

Code: Select all

Procedure MyProc(MyArray.l(1)) ;1 in brackets is the number of dimensions
    MyArray(5) = 100
    MyArray(10) = 1000
EndProcedure

Dim AnArray.l(20)
AnArray(5) = 10

Debug AnArray(5)
Debug AnArray(10)

MyProc(AnArray())

Debug AnArray(5)
Debug AnArray(10)

You can create an array in a procedure and return its address via ProcedureReturn @MyArray() with one proviso - the array must be created with a persistent scope, e.g. Global or Static else it's gone after the procedure finishes.
