You are confusing the -if- command and the -if- qualifier
which are quite different constructs. See

6/00 I have an if command in my program that only seems
to evaluate the first observation, what's going on?

Note that
. search if
would have pointed to this. Note also that
early = 1
is illegal in Stata. In your code you need -replace-. As whether -sex- is 1 or 2
appears irrelevant to your dummy, then unless you are dealing with three or more
sexes, code to do what you want you appear to be
gen early = (anypen1==1 | anypen2==1 | anypen3==1 | anypen4==1 | anypen5==1) & age < 60
Do please find out how not to send HTML in your mailer. A document referred to
in the Statalist FAQ leads to advice on this point.

I have a syntax question and help would be appreciated. I want to generate a dummy if certain conditions apply, but it does not seem to work as the early dummy is always 0.
-----------------
gen early=0
if sex==1 & (anypen1==1 | anypen2==1 | anypen3==1 | anypen4==1 | anypen5==1) & age < 65 {
early=1
}
if sex==2 & (anypen1==1 | anypen2==1 | anypen3==1 | anypen4==1 | anypen5==1) & age < 60 {
early=1
}
