Oh, I see. That makes sense, then. It can be done like this, though
it's a bit inefficient; Remind will spin its wheels trying to satisfy
the SATISFY clause after the last lesson. Luckily, modern computers
are so fast you don't even notice it.
# Count the lesson number starting from date "x"
FSET lesson_num(x) nonomitted(x, trigdate(),
"Mon","Tue","Wed","Thu","Fri","Sat")
PUSH-OMIT-CONTEXT
OMIT 2013-05-19
# 6 lessons, hence "<=6" in SATISFY clause
REM 2013-05-12 *7 AT 18:00 DURATION 1:00 SKIP \
SATISFY [lesson_num('2013-05-05') <= 6] \
MSG Salsa Level 1 - #[lesson_num('2013-05-05')]
POP-OMIT-CONTEXT

David.
