Note that in this case only your inner loop is doing any noticeable work (the printing), so you can just get rid of the outer loop. 

while ( <RULE> ) {
  if (/^STMT/.../^STMT/) {
    print unless /^STMT/;
  }
}

...or if you are into the whole brevity thang: 
/^STMT/.../^STMT/ and !/^STMT/ and print while <RULE>;
__END__
A
B
C
Y
Z

I used the ... operator instead of .. so that I could get away with the same pattern for both the left and the right sides of the operator, but I could have also used: 
  if (/^STMT\d+=BEGIN/../^STMT\d+=END/)
