I found the answer myself. Interval can not be defined dynamically with a variable. But you can use "units second" so my procedure becomes CREATE PROCEDURE i_hate_informix (prm_timeframe int) DELETE sometable WHERE someDateColumn.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
