Here's a dum question from a beginner. I have data from a source that uses -0.001 as a flag for missing information. How do I make Stata treat all such variables as missing? Is there an easy way to replace all -0.001s with dots?

A very easy command (if your variables is numeric)  is:

replace varname=. if varname==-0.001

Otherwise if your variable is a string variable, then you can destring it first as follows:

destring varname, force replace gen(newvar1)

replace newvar1=. if newvar1==-0.001
