If you or anyone can determine the version of the (1986) version, I'll adjust the filename accordingly. I'm presuming it's version 1.0, given that it predates the 1987 date of version 1.1 ??
The 1986 version is Kyan Pascal V. 2.x. The KIX-prompt "%" identifies it. Additionally, type AS<RETURN> at the prompt to see the assembler version 2.x. Surfaced in Summer 1986.
V.1 doesn't have an separate assembler - compiler and assembler are kept together in one program demanding more memory. That's why V 1.x requires an XL/XE.
The 1987 version of Kyan Pascal 1.1 is a user modded version, as far as we could figure out. Last official version of KP 1.x was version 1.3 in late 1985/early 1986, which is not found yet.
