Sheesh! So you expect the programmer who wants to do a one-off regex
search to write a macro to supply the argument in hex? Or perhaps a
general-purpose macro to convert its argument to hex and issue it back
to ISPF Edit?
FSVO "trivial".
BTW, how does one supply a regular expression to Edit in hex?
In contrast, in a POSIX shell with its escape facilities:
605 $ pat="s/foo\\/bar/\"wombat\"/"; printf '%s\n' "$pat"
s/foo\/bar/"wombat"/
606 $ echo foo/bar | sed "$pat"
"wombat"
607 $
Recherché, but effective.
