A QB45 program is showing a message, Overload in line 0 of module NSTKCNT at address 0724:30F5.
The NSTKCNT is a bespoke program for counting bats flying through an array of 2 rows of infrared beams. The computer is not counting the bats properly. I have downloaded the program before and after the error message showed and have EXE, MAK, and OBJ files. The computer is currently in Liverpool, U.K. but the programs could be sent on a USB data stick by post.
