Thank you all for the very helpful input and advice. 
It seems that -glm- has a general approach. It would be great if I can find how to check residual after the -logit-syntax. Will dig further and see how it goes. Otherwise, will use the glm approach. Thank you again!

-glm- has more of a one size fits all approach.  It doesn't have a 
lot of the customizations you see when using the more specific 
commands.  There was a thread a long time ago about how after -logit- 
some residuals are computed  "adjusted for number sharing covariate 
pattern" -- if that isn't the way you want to compute them you can 
use -glm- instead.  But logit restricts you the way it does because 
the options listed are the ones deemed more statistically sound.
