The $next
variable is set at the start of every iteration (and
at the non-BREAK
end) of looping statements, e.g. LOOP
,
SQL
, TIMPORT
etc. Inside the loop, it is equal to the
iteration count (counting from 1), plus the SKIP
value. At the
end of the loop, it is thus the value to use for SKIP
in a new
LOOP
or SQL
to continue iterating at the next value.
