Erase

Erase arrays

Description

Erase reinitializes fixed-size arrays, and releases memory allocated for dynamic-array storage. The required component, arrays, is a comma separated list of one or more (up to 7) array variables.

A faster way to do this is to simply force the recreation of the array:

myArray = []

Example

JavaScriptBASIC

// Erase Example
/* Erase reinitializes arrays */

Erase = function(arr) {
  var i;
  for (i=0; i<arr.length; ++i) {
    arr[i]='';
  }
}

PrintArray = function(arr, elements) {
  var i;
  for (i=0; i<elements; ++i) {
    NSB.Print("#" + i + ": (" + arr[i] + ")");  
  }
  NSB.Print();
}

var Children=new Array(3);
Children[0] = "Eric";
Children[1] = "Kenny";
Children[2] = "Kyle";
Children[3] = "Stan";
PrintArray(Children, 4);
Erase(Children);
PrintArray(Children, 4);

Rem Erase Example
'Erase reinitializes arrays
Dim Children(3)
Children(0) = "Eric"
Children(1) = "Kenny"
Children(2) = "Kyle"
Children(3) = "Stan"
PrintArray Children, 4
Erase Children
PrintArray Children, 4
Function PrintArray(arr, elements)
  Dim i
  For i = 1 to elements
    Print "#" & i&":","("&arr(i-1)&")"
  Next
  PRINT
End Function

Output

#1:    (Eric)
#2:    (Kenny)
#3:    (Kyle)
#4:    (Stan)
#1:    ()
#2:    ()
#3:    ()
#4:    ()
