The following PUB macro, under, takes a string as an argument and inserts
"∪", the PUB single word underline character in front of each word. You may
have to change the ←'s to _'s for the macro to work at MIT but the macro does
work. I don't expect that you will use it but a simple macro will work. By
the way; there was not a bug in PUB, but a stupid error in my use of scan.
The "ia" argument to scan was originally "a" which was incorrect.
.variable txt, token, space;
. turn on "∪"; txt ← "stuff";
. if txt=null then done else token ← scan(txt, space, null, "ia");
. if token=space then token else ("∪"&token); ⊃
. turn off; ⊃
