I guess I found the problem, but don't know a solution.
The following test code (same as the previous one except that I put them in
a function) now produces the same problem as my real code.
type Tech
cl::Array{Float64,1}
cm::Array{Float64,1}
function Tech()
this = new()
this.cl=[1:4]
this.cm=[6:10]
this
end
end
function mytest()
tech = Tech()
while true
println("input a choice")
ch = read(STDIN, Char)
if ch=='l'
y1 = include_string("tech.cl")
println(y1)
elseif ch=='m'
y1 = include_string("tech.cm")
println(y1)
elseif ch=='q'
break
end
end
end
