<= The LESS THAN or EQUAL TO Operator. (V2 <= 4) gives 1. > The GREATER THAN Operator. (V2 > V1) gives 1. >= The GREATER THAN or EQUAL TO Operator. (V2 >= V1) gives 0. IN The IN Operator. If the value of the variable is equal to any one of the values in a given ...
庞大的函数库确实给SASor们带来了非常多的方便,但是仓库式的SAS builted in帮助太杂乱,常常让人有一种“不识庐山真面目,只缘身在此山中”的感觉。有时,需要的函数找不到,找到的函数又不合适。其实SAS很体贴地不断增加高效的函数来精简你的代码和提高编程速度,可惜很多函数,SASor们并不知晓,常常看到别人使用的...

If you do not specify this option or if you specify a value for n that is less than or equal to 0, the seed is generated from reading the time of day from the computer's clock. The largest possible value for the seed is 231 1. You can use the SYSRANDOM and SYSRANEND macro ...
