Example 1: This sequence: 'SIN(π/6)' { 'SIN(π/6)' '1/2' } ↑MATCH returns '1/2' to level 2 and 1 (indicating a replacement was made) to level 1.

Example 2: This sequence: 'SIN(X+π)' { 'SIN(&A+π)' 'SIN(&A)' } ↑MATCH returns 'SIN(X)' to level 2 and 1 to level 1.

Example 3: This sequence: 'W+ƒ(SQ(5))' { 'ƒ(SQ(&A))' '&A' '&AŠ0' } ↑MATCH returns 'W+5' to level 2 and 1 to level 1.
