Norman meant that the dictum is to always explicitly state the method of
comparison within the instr function command rather than depend on any
default/global setting. He used the term text comparision to mean how
the
comparison is to be performed (binary or text) rather than that the
vbTextCompare be used as you appeared to interpret his suggestion. Futher
he envisioned this as a guiding principle in general across all functions
where appropriate - an Axiom

An admirably clear exposition of my intent!

Whoops!!! Sorry, I completely missed what you were saying. Yes, explicitly
specifying values instead of relying on defaults would be a good practice to
get into... and for object properties I always do that; but I am a long time
BASIC and VB user (started programming in BASIC back in 1981), so some "bad"
habits have become totally ingrained over the years. Relying on the default
start position of 1 and the default text comparison method of "case
sensitive" for the InStr function is one of those bad habits... after nearly
30 years of not specifying them, I probably will never remember to do so in
the "heat" of a programming session.
