How to format a string in CLIPS?
I need to format a string, but even if I copy a seemingly correct code, the CLIPS interpreter signals me an error.
(format nil "Integer: |% ld|" 12)
“I expect the output of "Integer: |12|" but the CLIPS interpreter signals me an error.
Solution
There should be no space between the % character and the format flag. Also the character 'l' is not a valid format flag.
CLIPS> (format nil "Integer: |%d|" 12)
"Integer: |12|"
