Toy programming language and compiler.

Language design

// This is a comment.

ptr += 123; // add 123 to the data pointer
ptr -= 123; // subtract 123 from the data pointer

*ptr += 123; // add 123 to the value that 'ptr' points to
*ptr -= 123; // subtract 123 from the value that 'ptr' points to

putchar(); // writes *ptr to stdout
getchar(); // reads the next character from stdin and stores it to *ptr

// while loop
while *ptr {
    // ...
}

Example

*ptr += 65;
putchar();
*ptr += 1;
putchar();
*ptr += 1;
putchar();
ptr += 1;
*ptr += 10;
putchar();
