(49G) OEIS A178225: Test for Binary-Palindromicity

[Gerald H]

In my own programming environment I use an XTable library where

Z1_

represents the pointer.

As not everyone has the same XTable library I avoid using Z1_ publicly, preferring to use the pointer, which should compile OK for everyone.

Your suggestion is a good idea, I mean more transparent, but could well confuse those not so experienced in Sys programming.
