Multi-BBS networks

Starting in 1988, the RelayNet, also known as RIME for RelayNet International Mail Exchange, allowed BBS's running PCBoard to join a network that exchanged messages with other BBS's in a system similar to the older FidoNet.

(PPL), which supported modifications and to a large degree replacement of most standard commands and processes. A compiled interpreter script written in PPL was called PPE (PCBoard Programming Executable). PPEs were generated by the PCBoard Programming Language Compiler (PPLC), which was an optional tool provided by Clark Development Company and was also available for purchase as stand alone tool. It was less than $100 by itself and less than $50 in combination with any BBS license. This allowed programmers to develop PPEs for PCBoard without having to purchase a PCBoard BBS license. Also optional and available by itself were the printed PCBoard manual and the printed PPLC reference handbook. The script language was introduced with version 15.0 and made this version of PCBoard even more successful than PCBoard V14.5. Various door programs were in use, including Sam Smith's Prodoor, which added a full screen editor and other features which were later included in PCBoard itself. The script language PPL and PPE's which became more and more available, increased the popularity of PCBoard and emerged by the mid nineties as the de facto-standard BBS system for

The last full release of PCBoard by Clark Development Company was version 15.3 in September 1996. Clark Technologies, a division of Clark Development Company announced on July 29, 1996 the availability of source code and OEM licenses for the PCBoard BBS software. The final release was 15.4 beta, which had a one-month trial period. Later, the lead software engineer from Clark Development Company released information on how to bypass the trial period timeout; the timeout had been inserted as a reminder and had not been intended to permanently disable the software.

However, PCBoard only had a few minor problems with the year 2000 (and 2001) and fixes were made available by several individuals. The last full release version of PCBoard, version 15.3, never really caught on and most systems that were online after 1997 continued to use the previous 15.2x versions of the software. PCBoard is still in use today by nostalgic BBS fans. There is a freeware

PPE/PPL groups

Thousands of PPEs were developed and published, often available free of charge, by individuals or scene groups. A number of commercial PPEs were also developed, mostly under shareware licensing. A number of release groups who were specialized in PPE and other PCB/BBS tool developments were formed, such as the French group Aegis Corp, the Russian group Brutal PPE/PCE/PRO Coders (BPC) and the German groups Peanuts (PNS) and Paranoia (PNA). Warez groups Such as PWA and DOD released several PPEs which were used by many sysops, including the PWA "NewScan" PPE, the PWA "Files-Reverse" PPE and the DOD "LARS Upload Processor". The French group Aegis Corp distributed a PPE De-compiler (PPLX) written by Lone Runner, which allowed the de-compilation of PPE binaries back to human-readable PPL code. Lone Runner also wrote the Aegis PPL compiler, which produced smaller and faster code than Clark Development's original PPL compiler. Other tools for PPE developers followed. Another PPE De-compiler was PPLDecompiler (PPLD) written by CHiCKEN, a member of the "Swiss Coding Division" of the group Electronic Rats (EcR).
