Hi all. I inherited some code for a program that I understand how the program works but I'm not sure what this part does - I think it has to do with making sure there's enough of a buffer for doing the matching / sorting / sql'ing that the rest of the program does (this is at the beginning of the program with a note that says 'DO NOT ALTER THIS CODE' - anyway, I was wondering if someone could "plain English" this for me - I'd like to understand more about what controls programmers can have with SAS for managing space, etc.

Thanks,

%global buffer ;

%macro getparms(libfil); %let lib=%scan(&libfil,1,.); %let mem=%scan(&libfil,2,.);

proc sql; select nobs, obslen into:nobs, :obslen from sashelp.vtable where libname=upcase("&lib") and memname=upcase("&mem"); quit; %put; %put Value of Lib= &lib; %put Value of Mem= &mem; %put; %let newnobs=%eval(&nobs+1000); %let buffer=%eval(&newnobs*&obslen); %PUT Value of buffer= &buffer; %mend getparms;
