Editing WWIV (section)

===Origins===
WWIV started out in early 1984 as a single BBS in [[Los Angeles, California]], run by [[Wayne Bell (computer specialist)|Wayne Bell]], who wrote the original 1.0 version in [[BASIC]] as a high school programing project, and shared the software with 25 of his friends.

As the popularity of WWIV spread in the mid-1980s, for practical reasons Bell switched to [[Pascal (programming language)|Pascal]]—specifically [[Borland]]'s [[Turbo Pascal]] 2.0—creating a [[compiled]] version of the BBS but distributing the [[source code]] for it to anyone who was interested in their own BBS. This encouraged sysops to develop new features for WWIV, and these ideas were released as "mods" that others could add to their own copies.

Shortly after releasing the 2.0 version, Borland updated the compiler to the 3.0 and 3.1 versions; WWIV's versions were revised to reflect the compiler versions. One of Turbo Pascal's strong features was the ability to easily "[[chain loading|chain]]" sub-programs and external modules into memory only as required; as the average available RAM for a program to load and run in [[MS-DOS]] was 384 [[kilobyte]]s,{{citation needed|date=December 2010}} this became a very important feature. "Chaining" allowed for online games and other utilities to be used with WWIV without having to add the new source code for the game and then recompiling the entire BBS again. These programs—referred to as [[BBS door|"chains" or "doors"]]—became very popular.
