OCaml source code for the following paper presented at FSCD 2021:  

Maika Fujii and Kenichi Asai
"Derivation of a Virtual Machine for
 Four Variants of Delimited-Control Operators"
6th International Conference on Formal Structures for Computation and
Deduction, FSCD 2021, July 17-24, 2021, Buenos Aires, Argentina
(Virtual Conference), volume 195 of LIPIcs, pages 16:1-16:19,

To compile, you need OCamlMakefile.  Write the location of the
OCamlMakefile in eval*/Makefile and make.  To execute the interpreter,
run ./interpreter and input the program into the standard input.
Example inputs:

1 + reset (reset (2 * reset ((fun y -> shift h -> y)
    	  	      	     (shift f -> shift g -> 3 + f 4))))

1 + reset (reset (2 * reset ((fun y -> control h -> y)
    	  	      	     (control f -> control g -> 3 + f 4))))

1 + reset (reset (2 * reset ((fun y -> shift0 h -> y)
    	  	      	     (shift0 f -> shift0 g -> 3 + f 4))))

1 + reset (reset (2 * reset ((fun y -> control0 h -> y)
    	  	      	     (control0 f -> control0 g -> 3 + f 4))))
