hope its clear for issue
#1 & 2 are pretty evident, the error tells the line number in the source with the problem, just fix it. #3 is pretty evident as well, the error will tell you the name of the variable that is not defined.
#4 is the only one that is a bit tricky if you haven't seen it before. The compiler did not find a return from the main procedure, and also no place that *INLR is set on. Either of those things will fix that one.
Odds are that you just included some typos in your code. Please don't paste the entire source and error listing, just read the errors, and go find someone in your company that can tell you where in the source listing to find the errors. Or if you are using RDi, you could just click on the error, and it will take you directly to the problem.
