Defining the nop construct.

§1.

enum NOP_IST

void Inter::Nop::define?Usage of Inter::Nop::define:
Definition - §3(void) {
    inter_construct *IC = Inter::Defn::create_construct(
        NOP_IST, NULL,
        I"nop", I"nops");
    IC->usage_permissions = OUTSIDE_OF_PACKAGES + INSIDE_PLAIN_PACKAGE + INSIDE_CODE_PACKAGE;
    METHOD_ADD(IC, CONSTRUCT_WRITE_MTID, Inter::Nop::write);
}

inter_error_message *Inter::Nop::new(inter_bookmark *IBM, inter_ti level, inter_error_location *eloc) {
    inter_tree_node *P = Inode::fill_0(IBM, NOP_IST, eloc, level);
    inter_error_message *E = Inter::Defn::verify_construct(Inter::Bookmarks::package(IBM), P);
    if (E) return E;
    Inter::Bookmarks::insert(IBM, P);
    return NULL;
}

§2. This in fact prints only in a stack backtrace, not in regular textual output, where any nop statements are simply ignored.

void Inter::Nop::write?Usage of Inter::Nop::write:
§1(inter_construct *IC, OUTPUT_STREAM, inter_tree_node *P, inter_error_message **E) {
    WRITE("nop");
}
