[EpiData-list] Command that Can affect Two diffrent Records

Hello, I have a questionnaire that i got from interviewing household members. However i was making sure that from each household i interview a male and a female respondent. You realize that some of the questions here for a household have got have the same answers eg Number of persons in the household, number of mosquito nets in the household etc. So, am inquiring to know whether there is any command i can include in my chk file to identify error between two records. I badly need your help, otherwise its so tiresome to check over 1500 records pair by pair. Thank you and regards
