Hi David,
You actually provided the solution yourself. Just wrap it up into
repmiss.ado:
program repmiss
version 8
syntax varname [if] [in]
local typ: type `varlist'
if substr("`typ'", 1, 3) == "str" {
replace `varlist' = "" `if' `in'
}
else {
replace `varlist' = . `if' `in'
}
end
However, when using post you can't get around knowing the variable types, I
believe.
Regards,
Morten

Hi everyone,
Is there a concise way to set a variable to a missing value if you don't
know its type (string vs. numeric)? This would be the reverse of the mi()
function -- reverse in that you are setting rather than testing the value.
Suppose I have a local v that contains a variable name, and I want to
replace the variable to missing.
Is there a way to do it in one easy command? Presently, I have been doing
something like...
local typ: type `v'
if substr("`typ'", 1, 3) == "str" {
replace `v' = ""
}
else {
replace `v' = .
}
(or other similar things involving macros). (And in another setting, I am
-post-ing a missing value, rather than replacing it in a variable.)
What I'd like is something like
replace `v' = universal_missing_symbol_that_works_regardless_of_data_type
I don't suppose it exists, but please let me know if I've overlooked
something.
If it doesn't exist, it's on my wish list.
