I can save an integer variable as upper case, but when I pull up the
project at a later time, this same variable has been changed to lower
case. For example "Dim NS as integer" appears at the start of the main
program, everything compiles and links and runs okay. No error
messages, and the program does what I expect it to do. Then I save the
project and exit the development system.

Next time I enter the development system, my code shows a lower
case "ns" throughout. NS is only declared in one place, but is used in
various subroutines that are part of the overall project. It did not
help to activate a debug flag to show where NS was changed during
program execution.

How can I check the library code to see if NS is defined elsewhere?
