Question

有没有人可以通过示例告诉Proc freq中的表和表之间的区别？

proc freq data= want;
table variable;
run;

proc freq data= want;
tables variable;
run;`

Answer 1

没有区别。该声明是TABLES声明，但SAS将默默接受TABLE作为同义词而不发出任何警告或注释。一些错过拼写只会产生警告，而其他拼写会导致错误。

1668  proc freq data= sashelp.class;
1669  tablex age name;
      ------
      1
WARNING 1-322: Assuming the symbol TABLE was misspelled as tablex.
1670  run;

NOTE: There were 19 observations read from the data set SASHELP.CLASS.


1671
1672  proc freq data= sashelp.class;
1673  tabl age name;
      ----
      1
WARNING 1-322: Assuming the symbol TABLE was misspelled as tabl.
1674  run;

NOTE: There were 19 observations read from the data set SASHELP.CLASS.


1675
1676  proc freq data= sashelp.class;
1677  tab age name;
      ---
      180
ERROR 180-322: Statement is not valid or it is used out of proper order.
1678  run;

NOTE: The SAS System stopped processing this step because of errors.
