select case问题!

[dwxq]

我用select case写满足某个范围值,该如和写!
如select case num
case num>0 to num<100
message="num小于100"
case num>100 to num<200
message="num大于100而小于100"
case else
message="num大于200"
ens select
是这样写吗?但是程序出错
显示如:
case num>100 to num<200
-----------------^
不明白!!!!!

to??

[cmsoft]

case num>100 and num<200

not use "to" but use "and"

[gage]

select num
case 1 to 100
end select

case (num>0 and num<100)
