some pseudo code to follow:
an out line would be:
if the code is not compiled the following will work, if it is (or is
going to be) then you need to create the arrays before hand. For the
example all arrays are text.
Array pointer($New_Array_Handles;0)
For ($i;1;$Number_Of_Arrays)
$Array_Name:= "Array_"+String($i;"00)
$Array_Pointer := Get Pointer($Array_Name) `gives a pointer to
Array_01, Array_02 ...
` assume all arrays are text
Array Text($Array_Pointer->;0)
` depending on what you are doing you can add data here
Insert in array($Array_Pointer->;$Where;$How_Many)
for($ii;1;$data_size)
Array_Pointer->{$ii}:=$New_Data
end for
` or
Append to array($Array_Pointer->;$Data)
` or you can add the array pointer to another array to
reference later
Append to array($New_Array_Handles;$Array_Pointer) `adds pointer to
new array
end for
To reference the specific element of an array through a pointer
$Array_Pointer->{$Element_Number}
To reference from the pointer array
$New_Array_Handles->{$Which_array}->{$Element_Number}
in some instances, you will find 4D chokes on second reference (context
dependent) so you can use either of the following as well:
($New_Array_Handles->{$Which_array})->{$Element_Number}
` or in 2 steps
$Pointer_To_Array:=$New_Array_Handles->{$Which_array}
$Pointer_To_Array->{$Element_Number}
