st: multiple conditions using an if statement?

[Michael Betz <betz.40@buckeyemail.osu.edu>]

Hi all--Is it possible to have multiple conditions using an if statement?

I'm trying to create several variables and sum all but two of them. 

Here's my code:

	foreach e in aborig afr asia can camer carber euro namer nonabor ocean samer{
		gen `e'_grt=pob_`e'+poc_`e'
		if "`e'"!="aborig" | "`e'"!="nonabor" replace sum_grt=sum_grt+`e'_grt		
		}

It executes, but does not perform the second part of the if command beyond the "or" operator ("`e'"!="nonabor"). It sums all the variables except the "aborig" one, but I need it to sum all the variables except both "aborig" and "nonabor". Am I doing something illegal here?

Thanks,
Mike
