Yeah, just to expand on what Dan said...only use B_CALL when you're calling
a ROM Point, or you're calling a routine on a different page in multi-page
apps.

Dan: The underscore had to be added because the B_CALL calls "&_label"...but
if you don't B_CALL it then you don't need the underscore.

HTH,

James.
