I'm still having problems with display file error messages. I have several programs that use display file error messages. When I turn on a specific message, the emulator should reverse-image the appropriate field, position the cursor in that field and inhibit typing (until the reset key is pressed). Client Access, at least, gets all of this right. tn5250 reverse-images the fields, but doesn't do the other things. I can't read 5250 streams, so I'm not sure what's happening (or not happening) here, but I've run an example and traced it. I just log in, go to a program that uses error messages, and make it use them. It looks like tn5250 is getting the data and understanding it, if I correctly understand InsertCursor: entered. InsertCursor: row = 8; col = 64 to mean that it wants to position the cursor to 8,64. That is where the first field in error is. In actuality, though, the cursor remains at (7,64), the position of the first input field. (I'm also assuming that these coordinates are 1-based.) The tracefile is attached.
