Is there any tools or compiler options to delete unused code and never called procedures in COBOL programs.
I mean I just want to cut the branch of a tree, and the clean-up of all sub-branches should be done automatically. |

Automatically? I don't think so......
I do know that code that is not referenced or considered unreachable by the optimizer is not compiled...... |

thank You..
Actually, I wanted it to be removed from source code. Anyway, does compiler listing displays unreachable code? |

Yes, I understood that.....

I (vaguely) recall seeing I-type error messages, you could try a little test program and see if you can generate some.... |

You can always check the cross reference listing of the compile step. If a paragraph is not referenced.
But then you have to deal with PERFORM THRU's and fall-thrus (from poor code).
suggest that before removing, you comment-out the code with comments as to why you are removing the code. |
