The peculiar evil of TRT is that "Everything looks like a nail."
You need only hammer on it enough with TRT.
In ISPF, the command:
FIND "foo;bar"
... fails for "Unterminated delimited string". But:
SAY "foo;bar"; /* in Rexx */
echo "foo;bar"; # in POSIX shell
printf( "foo;bar\n" ); /* in C */
In the all 4 languages ";" is a command separator. Only ISPF fails
to understand that in a quoted string it should not have that special
meaning. I suspect that ISPF does a misguided bottom-up search for
";" with TRT and deems it an unconditional command separator.
(Yes, I know that I can choose to sacrifice some other character as a
command separator, and avoid that in strings. At times I've used "¾".
But why should such mickeymouse be necessary?)
(Yes, I know that I can specify my search target in hex. Ugh! It
would be better if I could use sporadic hex escapes in otherwise
plain text.)
