Compiler for "Easy" language from "Etudes for Programmers" book (1978)

I was assuming it's something similar to PL/0 but the grammar looks quite extensive...
Joker_vD•3mo ago
Basically Algol, but with gratuitous "SET" to simplify parsing assignment statements, and without generic "BEGIN" braces: those are baked into "DO"/"THEN"/"ELSE".

You can probably straightforwardly translate it to Golang by running through a C preprocessor with an obvious set of macros.

ape4•3mo ago
The "FI" for "endif" is like bash.

The semicolons are like C.

The "PROGRAM" section is like COBOL.

kragen•3mo ago
The "fi" thing arose during the Algol-68 process, which Steve Bourne participated in, which is why he put it in his shell. (He would have put "od" there too to terminate "do" if it wasn't already used for a hexdumper.) You also find it in, for example, Dijkstra's Discipline of Programming.

Semicolons were widely used as statement separators in Algol-family languages, but in Easy they seem to be statement terminators, so they are apparently like C rather than like earlier Algol-family languages such as Pascal.

Pascal also had the "program" thing. I'm not sure if earlier Algol languages did?

IAmBroom•3mo ago
COBOL precedes Pascal.
kragen•3mo ago
Yes, of course it does. I didn't mean to imply that COBOL got it from Pascal. I meant that the practice was much more widespread than just COBOL, and given that the rest of Easy is clearly an Algol-family language very similar to Pascal or (then-draft) Ada, that's probably where he got it.
Rendello•3mo ago
If you're Stephen R. Bourne, "FI" is also like C!

The Etudes book is considered a classic, especially among FSU programmers-the book was licensed for a small amount, translated into Russian and used in many classrooms.
kragen•3mo ago
It's absolutely a classic!
