SAS dataset syntax error in data step Posted 01-27-2022 10:22 PM (1379 views) Hi all, I get the following syntax error when naming multiple datasets using hyphen in sas and it's very confusing. Could someone please shed some light on why this error comes up? Thanks in advance! 575...
When you submit a DATA step for execution, SASchecks the syntax of the SASstatements andcompiles them, that is, automatically translates the statements into machine code. SAS further processes the code, and creates the following three items 当向系统提交data步执行时,sas检验语法并进行编译(也就是...
The SAS DATA step is one of the most powerful and versatile software tools available for handling and manipulating data files, especially large data sets. It is also sometimes somewhat confusing to SAS programmers as to what the different statements do, what the correct syntax is for these ...
