What is different about the results? Give us more info! We have had a lot of
posts about the difference between the -if- qualifier and the -if-
programming command in the past...

Hello Statalisters,

I'm trying to convert some logical statements into nested if statements. I
feel the two statements below should give the same result but they do not.
What am I do wrong here?

Thanks in advance.


replace syphilis=1 if visit==1 & lbcd=="SYP_RPR" & (lbresc!="POSITIVE 1:128"
| lbresc!="POSITIVE 1:16")

if visit==1 {
    if lbcd=="SYP_RPR" & (lbresc!="POSITIVE 1:128" | lbresc!="POSITIVE 1:16"
) {
                replace syphilis==1
