I have this COBOL program in my mainframe:

Before testing it I must compile it but when I run the JCL it pops me a 0012 error.
This is the JCL:

//HERC0101 JOB (COBOL),

I’ve tried using another and simpler code, like this one:

       IDENTIFICATION DIVISION.     
       PROGRAM-ID. TEST2.            
       ENVIRONMENT DIVISION.        
       DATA DIVISION.               
       PROCEDURE DIVISION.          
           DISPLAY 'HOLA MUNDO!!'.  
           STOP RUN.                

And the JCL compiled it correctly, but with the other it showed me this error:
IEF202I HERC0101 LKED COMPILE - STEP WAS NOT RUN BECAUSE OF CONDITION CODES
The log shows all the procedure and after showing the code it shows this:
