===== Memcopy lockup =====

* In certain situations the <code><big>memcopy</big></code> command can lockup.
* A machine language utility that performs the same function as <code>memcopy</code> is available if <code>memcopy</code> fails.
* <u>mlcopy</u> is a short routine that replaces <code>memcopy</code> and is more reliable. It can be loaded into memory with a BLOAD command in your program, or with a basic loader that can be added to your program.
* In place of the <code>memcopy</code> command you would use 3 <code><big>POKEL</big></code> commands and a <code><big>CALL</big></code> command to engage the DMA engine.

 <code>POKEL $0903,data source</code>
 <code>POKEL $0906,destination</code> 
 <code>POKEL $0909,number of bytes to copy</code>
 <code>CALL $0900</code>
