U UNIVAC 1218 - Bitsavers

2.4.3 MOVE OPERATION
w
MOVE •
1) L The label for this operation is optional.
2) W - MOVE must always be presento
[ number 1 • [from address] • [to address]
of wordsJ
3) Vo- Specifies by an octal or decimal integer the number of sequential
words to be moved. Vo may never exceed 4000 octal or 2048Do A Vo
of zero is not permitted.
4) Vl- Specifies the first address of a block of data to be moved o It may
be expressed as an absolute address in octal or as a symbolic tag
plus or minus an octal or decimal integer. All the words to be
moved must be wholly contained within one bank.
5) V2- Specifies the first address to which the block of data is to be moved.
It is expressed the same as the VI operand. All the destination
addresses into which data are to be moved must be wholly contained
within one bank.
Examples of coding for MOVE operations are given below.
