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

The manual is still missing! Any hint for it is very welcome at any time. The only traces we have is the cover picture below and the titles:\\
__- PL65 Programming Manual Copyright © 1987 Noahsoft. For Atari models 400 800 XL and XE Series. 48K RAM Required. Issue 1__\\
__- 'Programmer's Card' with usefull addresses, Antic modes, Equates etc.__\\
__- yellow card with 'SY6500 Instruction Set Summary'__\\
Further some other docs including a manual for "Assembler" from QS Quality Software and the Newell 256KXLE upgrade\\
\\
Thank you spookt from AtariAge for your help in this case. :-)
* [PL65-Manual.pdf] ; size: 6.8 MB ; Thank you so much spookt from AtariAge for your help in this case and MrFish for the post processing. :-)
