Not the point. The leading-zero octal issue is that something
that appears mundane actually has a special meaning. I have seen
various ways for numeric literals to be represented in code, and
almost all of them have some weird characters to clue one in.
Examples:
=F'100' /360 & /370 Assembler fullword integer
1234H Z-80 assembler hexadecimal constant
0x1234 C's hexadecimal representation
If I had not heard of the leading-zero octal gotcha and someone
told me about it, it sounds that silly that I would want some proof.
Sincerely,
Gene Wirchenko
