Thanks for the posts, lesstjm.

I've tried using the full UNIX directory path in identifying the control file in sqlldr and also in the datafile within the control file, but the error message does not change.

I also made sure that SQLLDR.EXE is in my windows client system variables' path. (I don't know of any other system varaibles to change that would help here.)

I am not sure how to set or check the settings of my ORACLE_HOME variable in my profile. How would I do this?

Thanks again,
Steve
