Best minimal use of C: <robison@a.cs.uiuc.edu> Arch D. Robison	Arch D. Robison	University of Illinois	1304 W. Springfield Ave.	Urbana, IL 	61801	USAJudges notes:	Sites with punch card facilities will be happy to note that	the source deck can be re-collated with an ASCII sort.	Note that this program uses only a small subset of the	constructs that the C language supports.Selected notes from the author:	This program is a handy picoAPL interpreter written in C--.  It	outputs the evaluation of an APL expression from standard	input.  Functions are limited to dyadic +,-,x, and unary -;	numerals must be binary.  Parentheses may be used for	grouping.  For example:		101x111-100	prints:		1111	That is 5x(7-4) is 15.  (APL groups from right to left.)	Extending it to the full APL language should be trivial.	The C-- language improves the C language by removing superfluous	and confusing features: arithmetic, logical operations, shifts,	relationals, address-of, and flow control.  In fact, the only 	expressions retained are function calls, indirection, array 	assignments, the ',' operator, and sizeof.  Despite these	restrictions, the C-- program does arithmetic on arbitrarily 	large binary numbers.	To obtain a C-- reference, simply rip out the irrelevant pages 	from your K&R C manual.  To obtain a C-- compiler, simply rip	out the irrelevant bytes from your cc compiler.
