From: Jinto83 on 4 Apr 2010 00:31 Hi, suppose I want to define a bunch of ratios and I need to do it inside 2 loops: one loop on carbrand: Toyota, Ford one loop on variable: Sale, Profit data aaa; set bbb; SALETOYOTA=SALETOYOTA1997+SALETOYOTA1998; SALEFORD=SALEFORD1997+SALEFORD1998; PROFITTOYOTA=PROFITTOYOTA1997+PROFITTOYOTA1998; PROFITFORD=PROFITFORD1997+PROFITFORD1998; run; In reality the carbrand contains much more than just 2 companies, otherwise I would just type everything by hand. May I ask how to do this with array or any loop function? --- news://freenews.netfront.net/ - complaints: news(a)netfront.net ---

To that end you should reformat your variables so that CARBRAND and YEAR are variables rather implied by the variable names. If you have not yet entered the data then just enter it differently. |
