Using Epidata v2.0.2.29, the following (intimidating) message appears when entering an incorrect variable name in any command: *Internal error, report to info@Epidata.dk (Access violation at address 00404500 in module 'EpiDataStat.exe'. Read of address FFFFFFFC* Much friendlier is the message given in earlier builds: *Field 'varname' not found.*
