[Coco] technical assembler question

[Bob Devries]

dear friends,

I'm doing some writing in assembler for RSDOS (DECB). I don't do this often, 
you understand, so I've got a question:

When checking for a BREAK key, is it necessary yo do multiple reads of the 
POLCAT routine to ensure the key is not missed? At the moment i have this 
code:

 jsr [POLCAT]
 beq dskcont ;no key pressed, continue
 cmpa #BREAK ;that's #$03
 bne dskcont ;on BREAK, fall through to exit routine

Should I loop through that a few times to be sure I don't miss it or will 
that slow the programme down too much.

What do the "experts" do in this case?
