Some of these projects are very well done, so I suspect that a solicitation of such projects might produce some quite interesting Ada subset implementations, and certainly gallons of Pascal subset implementations (Augusta is really a Pascal subset done up in Ada syntax).

No, Ada compilers are not allowed to accept abbreviations. That's the point, if you make the maximum line length 2, then no valid programs can be written. All valid programs are rejected as exceeding the maximum line length. In Ada 83 there were no requirements on maximum line length values, so such a compiler is technically conformant to the standard :-) Sent via Deja.com http://www.deja.com/ Before you buy. ^ permalink raw reply [flat|nested] 19+ messages in thread

It is a compiler for a tiny language with a syntax that looks like Ada, but which as a language is really so far from Ada that it is misleading to call it an Ada subset -- technically correct -- after all a compiler that accepts no programs at all is technically an Ada subset compiler -- but not usefully identified as Ada.

You're right. It was in the January, March, May, and July, 1983 issues of Dr. Dobbs Journal (issues 75, 77, 79, and 81). It was a *very* small subset of Ada - no types defined by the user (no records and no enumeration types!), no packages, and the non-standard spelling "elseif." However, it *was* a good demonstration of hiding; a variable in a subprogram would properly hide a variable of the same name in its parent. It compiled to an intermediate language similar to P-code, which it then interpreted. But strangely, the intermediate file had the extension .COM! Needless to say, if you typed that file's name without invoking the interpreter, you crashed the computer. Augusta was later translated into Pascal.
