Hi
A while back I posted an error with genmod under V9.2 (see below)
After a bit more investigation I have determined its to do with the
amount of missing data in the class variables. If I exclude all the
missing data with a where statement it works OK. There is a related
SAS note about this here:

Original post:

Hi
I'm getting an error below  in GENMOD under V 9.2.
ERROR:  Write Access Violation In Task [ GENMOD ]
Exception occurred at (4166E8E3)
Task Traceback
Address   Frame     (DBGHELP API Version 4.0 rev 5)
4166E8E3  07C7E3CC  sasgenmo:mcn_main+0x6D8E3

7C80B729  07C7FFEC  kernel32:GetModuleFileNameA+0x1BA

The identical code below runs perfectly in 9.1.3
proc genmod data = long.sam2 descending;
  class  idalias time  trans      /param=ref;
model gpvisits=time trans / dist=bin link=logit type3;
repeated subject=IDalias/ ;

Removing the CLASS option PARAM=REF seems to fix it.

Anyone seen this?

Further info:
It appears that only the first obs has to have missing values for the
class variables for this error to occur. (thanks to Srinivas for this
info).
