Sets the name of the change file to be used. This name is used only if no interactive changes are allowed, and you do not specify ADDCIN, READRUNCHG or READCIN. The occurrence of MODVAR, GETCNSTCHG and so on in any screen will cause the change file to be ignored. In general it is best to use either READCIN or SETVAL commands to directly control simulation. The one exception to this is a situation where you are using a .vdi changes file to specify the location of Data that will be loaded using ODBC. In this case the file should be in the change files list.
