Abstract
In accordance with an embodiment, described herein is a system and method for achieving specific behaviors by intercepting file access calls in a mainframe application rehosted in a mainframe rehosting platform. A custom file handler can include a custom version of each of a plurality of default file operation application program interfaces (APIs) available in the mainframe rehosting platform, and can be invoked by the rehosted mainframe application. Each custom file operation API can perform one of a plurality of specific behaviors comprising changing a file access mode, appending a specific data field at the end of each record or line of a file, and performing one or more special post-handling actions. If the rehosted mainframe application cannot detect the existence of a custom file handler, a file access call can be directed to one or more of the plurality of default file operations APIs.
