PROC EXPORT to Stata: all variables converted to lowercase - problem

[Arsenio_Staer]

Dear all,

This should be a simple question. All datasets i export from SAS to Stata using code below end up with all variables low case although they were a mix of low and upper case in SAS.

PROC EXPORT DATA=lib.foo /* exporting for panel regression in stata for panel regression */

            FILE="t:\my docs\lib.foo.dta"

            DBMS=STATA REPLACE;

RUN;

Using R 2.13, same dataset and the code below,

write.dta(lib.foo, file=paste(df.project.path,"/","lib.foo.dta", sep=""))

conserves the casing of the variables. Have been searching around for the cause, but no luck. Would appreciate any help!

Thanks,

Arsenio

Still haven't been able to figure it out. It's a rather strange coercion given that both SAS and Stata support mixed case var naming.

Any advice?

you may find something information from the bottom part of the link https://communities.sas.com/message/119093#119093.  there are options (such as VALIDVARNAME) to control cases.
