st: RE: Assigning values from a list

My initial assumption was that you are looking at codes from the Diagnostic and Statistical Manual, but the context you have seems to be something else.  Remember, not everyone knows the acronyms you are familiar with.  I had another 'brilliant' idea that was wiped out when I checked the help file.  Austin's suggestion looks ok to me

Subject: st: Assigning values from a list

Hi All,
I was wondering if someone would help me with a basic programming questions.

I have 4 variables that are basically DSM codes and I would like to search
through those codes.

I would like to define lists of diseases and then pick which cases have those
diseases

So instead of writing 

gen virus=(var1==53.20) |(var1==54.42) |(var1==54.43) | /*
*/ (var1==76.00) |(var1==76.90) 

replace virus=((var2==53.20) |(var2==54.42) |(var2==54.43) | /*
*/ (var2==76.00) |(var2==76.90)) if virus==.

replace virus=((var3==53.20) |(var3==54.42) |(var3==54.43) | /*
*/ (var3==76.00) |(var3==76.90)) if virus==.

replace virus=((var4==53.20) |(var4==54.42) |(var4==54.43) | /*
*/ (var4==76.00) |(var4==76.90)) if virus==.


Repeat for several other categories of diseases - ends up with very long and
confusing code.


Is there a way of defining a list eg virus={53.20, 54.42, 54.43, 76.00, 76.90}

and checking to see whether var1-4 have values in the list?

Thanks in advance.
