What are some common challenges faced by entry level IBM RPG programmers when working with legacy systems?

Entry-level IBM RPG programmers often encounter challenges related to understanding and maintaining legacy code that may lack documentation or use outdated programming practices. Adapting to older development environments and integrating RPG applications with modern systems can also be tricky. However, most teams provide mentorship and code reviews, allowing new programmers to gradually build their expertise while contributing to essential business operations. Strong communication with senior developers and a willingness to learn are key to overcoming these initial hurdles.
