Banksel. Good practice?

Hi all,

Just wondering why people always seem to use RPO to change to banks, when banksel directive will change banks for you?

i.e


Is it not to be trusted or does it produce slower code than doing it by hand?
many thanks

Banksel produces two lines, like the example below, as long as you know what bank you're already in you don't need to use both lines - so it's slightly less efficient.

ok thnx nigel
