Here is a very quick explanation about move() and tab().
You can think of move() as move_relative(), and tab() as move_absolute().
Both of them move the "current" position (&pos) of the string scanning
environment, and both of them return the string between the old position
and the new position. When you say:
move(5)
you move &pos five characters/locations forward, but when you say
tab(5)
you actually move the position to 5. For example, if you have the string
"Unicon" and &pos is 3 (pointing at i),
move(4) gives "icon"
tab(4) gives "i"
tab() is the one to use usually with functions like many(), upto() and
any(), because the all give absolute positions in the string scanning
environment subject.
Unicon/Icon books cover these functions very well.
Cheers,
Jafar
