I second Maarten. In your application, however, this should not be a
problem, since you compare the value of one local macro to the value
of another:
if `hi'<`myseries_n' {
...
}
The -if- programming command is just the way to do that. Be careful
when using variables in the -if- programming command, though, as
Maarten explained. -if var1<`k'- is interpreted by Stata as -if
var1[1] < `k'-.
