Okay, I see. Like in
http://www.lb.shuttle.de/puffin/cbm4linux/manual/cbm4linux-3.html
where I saw the $60 ;-)

I see.

Okay.

I was afraid that unlstn would set $90 to zero because "there wasn't a
communication channel opened successfully in the first place so
closing it is a nop and therefore by definition successful". But if
this isn't the case i'll just LDA $90 after all operations. Dit I
understand you right that this is reasonable?

Many thanks,
