Programmer's Notepad (PN1) is an open-source text editor targeted at users who work with source code. It was released in 1998 by Echo Software (a trading name for Simon Steele). PN1's successor, Programmer's Notepad 2 (PN2), was released in 2002 and is now based on Scintilla. Despite being based on Scintilla, PN2 supports multi-line regular expressions for search and replace actions.
