Eric Armstrong proudly drove the following message along the Information SuperHypeway(TM) at breakneck speeds:

Yes. tab() goes to an absolute position, while move() goes a relative
amount from the current position (during string scanning, this value is
found in &pos).
Suppose you had the following due to previous string scanning:
&subject: "Nothing up my sleeve, Rocky"
&pos: 9
tab(12) would return "up "
move(12) would return "up my sleeve"
