I want to use retrieve convergence status of proc logistic from its ods table ConvergenceStatus, which contains a column 'status'. However, I cannot find a clear definition of this variable (by google search or in proc logistic manual) . It seems to me 0 indicates convergence and anything > 0 means some error. Is this true? Where can I find how this is defined?

The challenge with this approach is that it is hard to do automatic processing. For example in one model, I got a "quasi-completion" warning message in log. However, the corresponding text in the "Reason" column doesn't contain "WARN" or anything similar. For this particular case, I can hand-code the warning message in my program. But what if another convergence issue occurs? I cannot find a list of all warning msgs in proc logistic.

Did you check ConvergenceStatus table when had warning message "quasi-completion" warning message in log. You will have the same message in ConvergenceStatus table. I think there are only two possible messages that ConvergenceStatus table may have
Quasi-complete separation of data points detected. 1
Convergence criterion (GCONV=1E-8) satisfied. 0
