Binary manipulation in Forth

[ctrilsbach]

Are there any words to logically shift binary similar to C's >> & << in Forth?

If not would they be difficult to create? Presumably assembler would have these commands.

For single-cell integers there are lshift, for shift left, rshift, for shift right (i.e unsigned shift right), and arshift, for arithmetic shift right (i.e. signed shift right).

For double-cell integers there are 2lshift, for shift left, and 2rshift, for shift right (i.e. unsigned shift right). There is also 2arshift, but I found a significant bug when I was testing it this morning, so it will need more work.

Great thanks Travis.

There is now a fix to 2arshift in the repository, in both the master and devel branches.
