Data Movement Instructions
Section 3-8
Description
XFER(070) copies N words beginning with S (S to S+(N–1)) to the N words
beginning with D (D to D+(N–1)).
It is possible for the source words and destination words to overlap, so
XFER(070) can perform word-shift operations.
Flags
Precautions
Be sure that the source words (S to S+N–1) and destination words (D to
D+N–1) do not exceed the end of the data area.
Some time will be required to complete XFER(070) when a large number of
words is being transferred. In this case, the XFER(070) transfer might not be
completed if a power interruption occurs during execution of the instruction.
Example
When CIO 000000 is ON in the following example, the 10 words D00100
through D00109 are copied to D00200 through D00209.
