You can specify options that control the behavior when debugging 
      Micro Focus COBOL in 
      Tools > Options > Debugging 
      . 
    
 
  
 
     
       
        - COBOL Debugging Settings > Step into inline PERFORM statements when using Step Over 
        
 
 
        - By default, 
          Step Over (F10) skips inline PERFORM statements. 
        
 
 
        - Check this option to enable stepping into inline PERFORM statements when you use 
          Step Over. Works with native code only.
