PROC HPBIN Continuous and special characters

[meighanj]

I have a continuous variable which I want to run PROC HPBIN on, however, the problem is that there are a number of special characters in the data. When I run the HPBIN it treats the special characters as continuous data and messes up the bins. Is there anyway for me to specify for the special charcters to each go into their own bin and then bin the rest of the data normally?

If you mean you have values like -999 in the data, then I think the only thing you can do is re-code those as missing values, then all the missing values will go into Bin 0 and won't affect the binning of the regular values.
