The E-DataAid application offers a security feature allowing a user to set security options when supplying a valid password. For example, in E-DataAid, a user may set the security options to disallow edits to subject and session number, or to disallow all edits. When a source file containing a variable with a certain security level is merged into a target file containing the same variable with a different security level, the variable in the target file will have the security level that is the stricter of the two files upon completion of the merge operation.
The Admin Open command is used to open a data file as an Administrator, which permits access to security settings. Once a file is opened by an Administrator, security restrictions for that file may be set using the File Security command on the File menu. Refer to the article GENERAL: Variable Settings  for information pertaining to security restrictions.
