When I run a series of commands to generate new variables in a do file and realize I made a mistake on one of them, I would like to fix the mistake, highlight the section of commands, and run the selection. When I do this, Stata says the generated variables already exist. Sooooo, I need to drop each variable I created in the series of commands, and then re-run them. I assume this is a way Stata has to prevent accidently replacing a variable.
QUESTION: How can I have the gen and egen commands replace the variables
I want it to replace rather than having to first drop them???

RESPONSE:
If, in your programs, you insert the line
capture drop varname
just before the
gen varname = __function__
or
egen varname = __function__
instruction,
then Stata will drop varname if it already exists, or do nothing if it
doesn't, and proceed with the gen or egen function you require.
