NCLcut is a specialized tool designed to efficiently shorten large NCL (Numerical Control Language) files used in post-processor runs. Developed for scenarios where extensive NCL files lead to prolonged testing times, NCLcut allows users to selectively trim these files, focusing on essential parts for testing.

• Open File: Load NCL files (.ncl) through a user-friendly dialog window.
• File Information Display: Shows the filename, path, and file size.
• Sequence Display: Lists sequences with details like running number, sequence name, feature number, line count, and tool presence.
• Selective Shortening: Choose individual or multiple sequences for trimming.
• Customizable GOTO Limit: Set a limit for the number of GOTO movements (default: 30).
• Cutting and Deleting Options: Trim or remove selected sequences.
• File Size Update: View the new file size post-modification.
• Save Options: Overwrite the existing file or save as a new file.
• Sequence Preview: Non-editable window to view the start of the selected sequence.

• Line-by-Line Reading: NCL files are read into memory one line at a time.
• Sequence Detection: Identifies sequence start (->FEATNO/), end (->END/), name (PPRINT / NC SEQUENCE NAME:), tools (LOADTL or TURRET), circles (CIRCLE), GOTOs, continuation lines ($), and file end (FINI).
• Object Creation: Each sequence's data is stored in an object, with planned changes saved initially in the object.
• Continuation Lines: Ensures 1:1 output of continuation lines as in the input file.
• Circle Handling: Prevents separation of GOTOs following a CIRCLE command.
• End-of-Sequence Handling: Cuts only GOTOs at the end of a sequence, keeping technology instructions intact.

• Programming Environment: C++, Visual Studio 2019, preferably using MFC.
• Platform: Windows executable, standalone.

1. Open File: Click 'Open File' to load an NCL file.
2. Select Sequences: Choose sequences to shorten or delete.
3. Set GOTO Limit: Adjust the number of remaining GOTOs if needed.
4. Modify File: Use 'Cutting' or 'Deleting' options as required.
5. Save Changes: Click 'Save' or 'Save as' to finalize changes.

This tool is designed to streamline the process of shortening NCL files for testing purposes, ensuring efficiency and accuracy in handling large files.
