Is there an equivalent to a SWP instruction that can be used in studio 5000?
Migration guide says there isn't one.

I've been using SWPB for a long time.
As far as I can remember, it does the same thing as SWP did, except it has some more options for swapping bytes in DINTs.

I just did a little more digging and it looks like the SWP can swap an entire string.
In Studio 5000, SWPB can only be used INTs and DINTs one at a time..

You can copy (COP) the string to a DINT or INT, then use the SWPB, then COP back to the string. There may be a better way but I know this works.
