Re:Tips on dynamic arrays, and help with dynamic arrays of records
You can create an array of Records this way..
Type Myrecord = Packed Record
name:string[128];
streat:string:[64];
end;
var
Myarray:array[0..50] of Myrecord;
// now that is a Fixed size of records.., another wayu you could do this.
{$R-}
Type
MyArrayType = Array[0..0] of MyRecord;
var
MyArray:^MyArrayType;
begin
GetMem(MyArray,100*Sizeof(MyRecord)); // Space for a 100 records;
// now to access a record..
MyArray^[10].name := 'John Smith'; //set name in record 10.
// when done with record space..
FreeMem(MyArray, 100*SizeOf(MyRecord));
End;
