// Phase 92 P2-3: P5b Test That Matches Pattern Recognizer
//
// This test is designed to exactly match what the pattern recognizer expects:
// 1. Body statement with simple ch assignment
// 2. Break check: if ch == "\"" { break }
// 3. Escape check: if ch == "\\" { i = i + 2 } else { i = i + 1 }
//
// Expected behavior (simulated string "a\\b\"c"):
// - i=0: ch='a', not quote, not escape, i=1
// - i=1: ch='\\', not quote, IS escape, i=3
// - i=3: ch='\"', IS quote, break
// - Output: 3
