I think you're just lucky in this case. Without knowing exactly which
fields are involved with PMPCNV:*input and RF$PM:*output I can't say for
sure, but I can only think of one way this could work.
When you "EVAL toDS=saveDS", you are essentially treating each DS as a
big character variable. So, if the layout of each matches up to the
length of toDS, you will end up with everything in its right place since
the first %len(toDS) bytes of saveDS will be copied to the memory
starting at %addr(toDS).
If that doesn't make sense I can give an example. Just let me know.
