Solutions for bad data?

[cash@xxxxxxxxxxx]

Anyone have solutions for finding bad data?

Occassionally I get weird results on some of my systems and 
when I trace it down, it turns out to be bad data.  For instance, on 
1/24/01 daily data for MMM, it had a H of 217 when it should have 
been 110.63.

I'd like to right a EL routine that checks for things like this and 
spits out the out of line ones into a file so I can edit the data.  But 
I'm not sure what things to look for.

Before I dive into this head long, has someone else done 
something like this before and would yo be willing to share the EL 
code?

Thanks,

Cash
