When I try to open the external text editor for this file. It says :
Cannot open the external text editor for this file. Suggestion:
make sure the text editor is set in the EDITOR or VISUAL environment
variable and supports a filename as an argument.
I must have failed to do something when I was setting up this program
on the nqueens problem. Please tell me how to fix this problem.
Any help appreciated Thanks in advance.
