Page Length Command Replacement for PCBoard - Improved User Input Handling

This documentation outlines the replacement for PCBoard's Page Length command, designed by Jesse Keene. The script enhances user experience by validating inputs and dynamically adjusting the page length based on user specifications (0-99). If the input is invalid, the program prompts the user again, ensuring all inputs are coherent and giving clear instructions on what values are accepted. For improved aesthetics, ANSI enhancements are included to provide a better visual cue. Feedback is welcomed; reach out to Jesse Keene at spacecb@deeptht.armory.com.
