Hello Nick, Thank you. I tried reading/running your code that uses syntax. I will be frank with you, I couldn't follow your code even after spending quite some time trying to follow. The problem I think is due to too many new keywords i.e. syntax, marksample and touse. I looked for them in manual and still not sure. I am posting the similar question in a little diff way. I am hoping that might break the ice. date var1 var2 var3 var4 var5 var6 01jan2010 1 3 5 2 1 6 02jan2010 6 2 1 5 6 7 03jan2010 4 2 5 7 8 1 This was my program to rank and it works... clear args firm_id start_date end_date graph_type if "`graph_type'"=="rank" { collapse (sum) var* if tin(`start_date',`end_date') local counter 1 foreach x of varlist var* { if `x'!=`firm_id' & `x'>`firm_id' { local ++counter } } list di " I rank `counter' " exit } The problem is I want to be able to ignore certain variables and I want to be able to list those variables as arguments preferably after my 4 initial arguments. So, if I want to exclude var5, then do filename var4 01jan2010 03jan2010 rank var5 (Note: I want to have liberty to enter any no of variables to be ignored in my arguments....) My idea is to have ignored variables in some kind of loop and reduce those variables from my varlist one by one. Once the forloop is done, create a new varlist containing only the variables I am interestd and rank them. Let me know if I can make it any clearer. Thank you very much and I am really sorry to be knocking at you multiple times...

The problem with this code is you have to edit the code everytime you want to change the variables to be ignored. That is exactly why I wanted to pass those variables as arguments.

I didn't write the actual program because it is too long and I am afraid it might bore you guys. I would be more than happy to put the actual program and actual problem I am facing if you are interested. But, I am going to be using similar concept somewhere in my actual program. > >>> > >>> > >>> > >>> Thank you very much for your time, > >>> > >>> Tashi > >>> > >>> > >>> > >>>> Date: Sat, 31 Mar 2012 17:47:55 +0100 > >>>> Subject: Re: st: passing indefinite no of arguments > >>>> From: njcoxstata@gmail.com > >>>> To: statalist@hsphsun2.harvard.edu > >>>> > >>>> Frankly, this is very confused.
