Okay in that case you can explicitly type those names or use var1--varN (double dash variable list)

[walterwang]

course names look like:

CPC10108 (11) CPC10111 (11) CPC20111 (11) CPC20112 (11) CPC20211 (11) CPC20712 (11) CPC20812 (11) CPC30111 (11) CPC30116 (11) CPC30211 (11) CPC30216 (11) CPC30313 (11) CPC30318 (11) CPC30411 (11) CPC30413 (11) CPC30508 (11) CPC30511 (11) CPC30611 (11) CPC30708 (11) CPC30711 (11)
and there are more than 100 courses.
how to write variable?
Many thanks.
