如何理解sas语句的语法格式，好像它不同于伪代码，哪里有解释的说明吗？例如下面是DATA的语句的语法格式（详见ＳＡＳ帮助文档），怎么样才能将其转化成SAS的语句。 DATA <data-set-name-1 <(data-set-options-1)>> <. . .data-set-name-n <(data-set-options-n)>> </ <DEBUG> <NESTING> <STACK = stack-size>> <NOLIST>;

DATA _NULL_ </ <DEBUG> <NESTING> <STACK = stack-size>> <NOLIST>;

DATA        view-name <data-set-name-1 <(data-set-options-1)>> <. . .data-set-name-n <(data-set-options-n)>> / VIEW=view-name <(<password-option><SOURCE=source-option>)> <NESTING> <NOLIST>;

DATA        data-set-name / PGM=program-name <(<password-option><SOURCE=source-option>)> <NESTING> <NOLIST>;

DATA VIEW=view-name <(password-option)> <NOLIST>; DESCRIBE;

DATA PGM=program-name <(password-option)> <NOLIST>; <DESCRIBE;> <REDIRECT INPUT | OUTPUT old-name-1 = new-name-1<. . . old-name-n = new-name-n>;> <EXECUTE;>
