You are encouraged to solve this task according to the task description, using any language you may know.
RCSNUSP is a set of SNUSP compilers and interpreters written for Rosetta Code in a variety of languages. Below are links to each of the versions of RCSNUSP.
An implementation need only properly implement the Core SNUSP instructions ('$', '\', '/', '+', '-', '<', '>', ',', '.', '!', and '?'). Modular SNUSP ('#', '@') and Bloated SNUSP (':', ';', '%', and '&') are also allowed, but not required. Any extra characters that you implement should be noted in the description of your implementation. Any cell size is allowed, EOF support is optional, as is whether you have bounded or unbounded memory.

Seed7
The interpreter below implements Core SNUSP:
<lang seed7>$ include "seed7_05.s7i";
const proc: snusp (in string: sourceCode, in integer: memSize, inout file: input, inout file: output) is func
local var array string: instructions is 0 times ""; var array char: memory is 0 times ' '; var integer: dataPointer is 1; var integer: instrPtrRow is 0; var integer: instrPtrColumn is 0; var integer: rowDir is 0; var integer: columnDir is 1; var integer: helpDir is 0; var integer: row is 0; begin instructions := split(sourceCode, "\n"); memory := memSize times '\0;';
for key row range instructions do if pos(instructions[row], '$') <> 0 then instrPtrRow := row; instrPtrColumn := pos(instructions[row], '$'); end if; end for;
while instrPtrRow >= 1 and instrPtrRow <= length(instructions) and instrPtrColumn >= 1 and instrPtrColumn <= length(instructions[instrPtrRow]) do case instructions[instrPtrRow][instrPtrColumn] of when {'>'}: incr(dataPointer); when {'<'}: decr(dataPointer); when {'+'}: incr(memory[dataPointer]); when {'-'}: decr(memory[dataPointer]); when {'.'}: write(output, memory[dataPointer]); when {','}: memory[dataPointer] := getc(input); when {'/'}: helpDir := rowDir; rowDir := -columnDir; columnDir := -helpDir; when {'\\'}: helpDir := rowDir; rowDir := columnDir; columnDir := helpDir; when {'!'}: instrPtrRow +:= rowDir; instrPtrColumn +:= columnDir; when {'?'}: if memory[dataPointer] = '\0;' then instrPtrRow +:= rowDir; instrPtrColumn +:= columnDir; end if; end case; instrPtrRow +:= rowDir; instrPtrColumn +:= columnDir; end while; end func;
- SNUSP implementation of Hello World.
const string: helloWorld is "/++++!/===========?\\>++.>+.+++++++..+++\\\n\
\\\+++\\ | /+>+++++++>/ /++++++++++<<.++>./\n\ \$+++/ | \\+++++++++>\\ \\+++++.>.+++.-----\\\n\ \ \\==-<<<<+>+++/ /=.>.+>.--------.-/";
const proc: main is func
begin snusp(helloWorld, 5, IN, OUT); end func;</lang>
- Output:
Hello World!
