Hi tupp,
It didn't occur to me that one might need remarks in the imported file. Is it the same as comments, i.e. you want to put some information related to horses into that file but want the program to ignore it?
I'll add this to the "wish list", but right now you can safely separate your comments from the selections' names with a tab character (on your keyboard). E.g.:
My Fair Lady[tab]comment1
Rusty lad[tab]comment2
etc.
MF Pro will regard those comments as imported values, and will put them in imported_1 variables, but there will be no impact on the functionality, unless of course you already use some imported values in your text file.
