The system was written in [[wikipedia:Paoli, Pennsylvania|Paoli]], by Jim Ryan, Glenn Martin, Jim Williams, and Ken Carvin. Ron Murray joined the team in 1974. Due to the physical location, just outside of Philadelphia, the team had close contact with [[Ken Iverson]] and [[Adin Falkoff]], who were at the [[IBM]]'s [[wikipedia:Philadelphia]] office at that time. | |||
Though an an independent [[wikipedia:ALGOL 60|ALGOL 60]] implementation, it was based on the ideas from APL\360, and borrowed some ideas from [[APL.SV]].<ref>Private email from Ron Murray. 25 May 2001.</ref> | |||

Despite its similarity However, it also differed in quite a few details:<ref>[[wikipedia:Burroughs Corporation|Burroughs Corporation]]. [http://www.softwarepreservation.org/projects/apl/Manuals/APL700UserReferenceManual User Reference Manual] (5000813). 1975.</ref> | |||
* The statement separator was a semicolon (<source lang=apl inline>;</source>) rather than the conventional diamond <source lang=apl inline>⋄</source> and statements in such a so-called ''list'' were evaluated from right to left, much as if the semicolon was the Left [[identity]] function (<source lang=apl inline>⊣</source>). | * The statement separator was a semicolon (<source lang=apl inline>;</source>) rather than the conventional diamond <source lang=apl inline>⋄</source> and statements in such a so-called ''list'' were evaluated from right to left, much as if the semicolon was the Left [[identity]] function (<source lang=apl inline>⊣</source>). | ||
* In primitive pairs with both a last and first [[axis]] version, for example <source lang=apl inline>/</source> vs <source lang=apl inline>⌿</source> and <source lang=apl inline>⌽</source> vs <source lang=apl inline>⊖</source>, the first axis version would use the [[function axis]] syntax to indicate the applicable axis counted from the ''last'' axis rather than from the first axis. For example <source lang=apl inline>⊖[1]</source> was equivalent to <source lang=apl inline>⌽</source> just like <source lang=apl inline>⌽[1]</source> was equivalent to <source lang=apl inline>⊖</source>. | * In primitive pairs with both a last and first [[axis]] version, for example <source lang=apl inline>/</source> vs <source lang=apl inline>⌿</source> and <source lang=apl inline>⌽</source> vs <source lang=apl inline>⊖</source>, the first axis version would use the [[function axis]] syntax to indicate the applicable axis counted from the ''last'' axis rather than from the first axis.
