A class to hold a memoryblock.

Example

dim m as new MemoryBlockMBS

if m.Create(2000) then
  
  // copy struing into memory
  m.Memory.StringValue(0,5)="Hello"
  
  // and read again
  MsgBox m.Memory.StringValue(0,5)
  
end if

Xojo's memoryblocks have two bad things:
- they are limited to 1 GB on Mac OS X and Mac OS Classic
- they take a lot of time to create them
- they take a lot of real memory

Xojo allocates the memory and fills it with zeros.

The plugin in contrast uses zero filled pages to create the memoryblock which nearly take no time to create them and it does only need virtual memory until the memory is really used which saved swapping space.
