.back — the same move as .up, under the word a hand reaches for.

The caller ran BEFORE the frame it called, so back in execution order IS outward. gdb spells back as an abbreviation of backtrace, which is its prefix-matching rather than its judgement, and reads wrong at a prompt where somebody typing "back" means "take me back".

Its own function rather than goToCallerFrame with a spelling passed in, so that every command in this file stays a plain main that takes only what a command is given. There is deliberately no .prev: a third word for one move invites a .next to answer it, which is already the step-over command.

import { goBackToCallerFrame } from './frames.ts';

import type { ReplContext } from './command.ts';

// Defined, not invoked: it reads a stopped page.
function example(repl: ReplContext) {
  return goBackToCallerFrame(repl, '1'); // one frame back, which is one frame out
}
