I kinda like the concept, but a lot of literals we use are just 4
characters, so it does not scale down easily.
One of the other thoughts mentioned was lower-case vs. upper-case. Maybe
a macro that accepts upper-case, but stores it as lower-case, then ORs
it with x40 when moving it:
TAGIT MY_TAG,ABCD
that generates:
MVC MY_TAG,=C'abcd'
OC MY_TAG,=C' '
I would have to set my editor a little different when viewing dumps, but
it may work better than the original MVCIN thought. (I normally use
"case mixed ignore" in XEDIT.)

Yes.
CLI for the first character followed by a CLC for the remainder would have
the advantage that probably more than 9 times out of 10 the CLI would be
sufficient.
I had imagined that the OP planned to search not with a program
but intereactively in a browser.
How likely are false positives? Are there any characters to avoid
perhaps because they might be likely in Packed decimal values.

The use of MVCIN to set a data area eyecatcher is incredibly
inefficient.
But is the code path heavily traveled?
