'
I don''t know if this is fixed. I don''t recall seeing a message on it.'
'
Please note that whether this works may be different on an 1100, an 1108, and an 1132, because it involves the microcode and the microcode is different on all three machines. '
'
Will 1100Support be in a position to test all three machines, at least for some amount of time to check over ARs tht might be machine-specific?'

------------------------'
'
Don Cohen at ISIF reports the following':'
'
Even with (OVERFLOW T), (IQUOTIENT MIN.INTEGER -1) = MIN.INTEGER -'
I get the feeling that whoever wrote the microcode decided that integer'
division could never overflow, and forgot this special case.'

'
This is just AR 221.  It was fixed some time ago.  Microcode isn''t involved since all three machines "punt" out when either argument to IQUOTIENT is something other than a SMALLPOSP.'
