Hi Joe,
Stata shuts down. There may be an error message, but it flashes past on
the way out, so I don't know what it is.
I found a work around (save the list of ICD9 codes occurring in my
dataset, check and clean those, then merge back on, so for now I'm not
going to try anything else. Strange though.
thanks,
Jeph

Jeph,
When you say "causes Stata to crash" what exactly do you mean? There's an error message? Stata shuts down? Stata seems to stop working?
In my experience -icd9- is very slow; I use it on data sets that are about same amount of memory but fewer observations (5-10m). Among other things, it does several sorts and a merge with the ICD9 code file.
Absent any other information I would try a -set trace on- and see where the crash is occurring.

Subject: st: -icd9- crashes Stata
All,
I have been trying to use the Stata command -icd9- to process a variable containing (yes) ICD9 codes. The same fragment of code ran correctly in the past, but now
capture : icd9 dxcode, check gen(invalid)
causes Stata to crash every single time. The dataset is large (~60m obs,
5gb) but Stata has no problem eg merging or sorting the same dataset, so I don't see why that should be an issue. Any thoughts? Any alternatives?
I do not often work with ICD9 codes.
-dxcode- is str7, if that matters.
thanks,
Jeph
