!!!PL65 Copyright (C) 1987 Noahsoft |
Here's a working disk image of PL65 for anyone who wants to try what must be the rarest of Atari 8-bit languages. To use it, boot with SpartaDOS (an X cart image in one of the emulators is a good development environment) then run PL65.COM and choose from the various menu options. SAMPLE.PRG is a useful example program to figure out some of the finer points of the language (there's no manual on the disk) and S.OBJ is the compiled source. Little or no third-party documentation exists and I don't have a manual. I have one in-depth magazine article (in 8:16, BaPAUG's magazine, written by Simon Trew). |

!Background |
PL65, like the better-known [Action], is a high-level ALGOL-derived language intended to produce high-performance code in a more readable format than [assembler]. The two languages share much in common in overall terms and even syntax and structure. The main difference is that PL65 includes a STRING type, something Action! lacked, but like Action!, PL65 also lacks a FLOAT type. |
|
One unique feature of PL65 is that it includes two full-screen editors. The main editor is KED, and includes modern features like indentation support, search and replace, and block copy/paste. A second editor, the "micro editor", is included in the compiler program, allowing you to make minor changes without having to switch programs. |
|
PL65 allows libraries to be referenced in a program using the INCLUDE directive, in a fashion largely identical to C's #include. However, it also includes the LINK command, normally placed at the end of a file, which allows several files to be stitched together into one larger file. The difference is that INCLUDE begins compiling the referenced file when it is seen in the code, whereas LINK occurs only when the current file is completely compiled, even if the LINK is placed higher in the code. |

The package consists of a compiler, editor, library and a sample game. |
