I'm studying the copydata example to learn how to extract several variables from a file identified in a COMMENT LEGAL statement. In A3.chk, the statement "TYPE COMMENT atransfer" appears. What is atransfer? I don't see where it has been defined as a variable and I don't find it as a system variable. Further, the program seems to be parsing the string in atransfer according to the position of punctuation. Where is the format of this string defined?
Perhaps to be a bit more explicit: I have file with a list of CHWs: District, Village, CHW name and a survey conducted by the CHWs. As the data is entered for the survey, I'd like to present pick lists to facilitate entry. The data is quite strictly hierarchical: Villages occur within Districts, an CHWs live in villages.
Thank you,
