Thanks to all who answered.

I did check as many datasheets as I could find, again, this is about TRIS
appearing in a 14 bit core datasheet where I never saw one. And appearing a=
t
encoding level, at that (i.e. not TRIS in .asm but the equivalent of 0x0065=
 in
..hex !).

TRIS is indeed a valid instruction on 12xxx and other 12 bit cores. Frankly=
, I
do not know what to make of it, as it does not appear in the instruction ta=
ble
"PIC16F62X INSTRUCTION SET".=20

BillW's notes wrt. his datasheet are noted, I will find that datasheet and
compare with it. I am using DS40300C which has no mention of tris anywhere.

Are there any more easte egg "grandfathered" opcodes in modern pics? Such a=
s,
for example, option (the opcode, not the register) ?
