This is the log of mmy code which does not give an error but still if I try to reference the value n_lcg I get an error that the value cannot be resolved.
How do I resove this error?

Thank you!

We are not seeing all of your program. Specifically you have not shown us the full definition of the macro CHECK_N (which currently has all the shown code commented out). Nor do we see where or how the macro variable N_LCG is called.

Consider using a %PUT N_LCG &N_LCG; statement to verify that the macro variable exists and has a value.

My guess is that this is a "timing" thing. The warning is likely coming during the compilation of the %check_n macro which occurs before execution time (when your PROC SQL runs).
