#189431 - Error correction
Responding to: Hal Albach's previous message
In my previous response I said:
"When you move U or L to A, set bits 5 & 6 in A so that RS & RW won't be modified when you dump A to the port."
It should have been "When you move U or L to A, set the bits in A.5 and A.6 to what you want RS & RW to be so that when A is dumped to the Port the control bits will be correct."

The initial sentence makes it sound like I wanted the OP to set bits 5 & 6 to 1's when I intended to set UP the bits accordingly.

Sorry for any confusion.

Hal
