put (_all_)

[myraao]

Someone gave me code a while back with put (_all_) in it. I went to search for another use for it but can't find the documentation. 

data _null_;
file "k:\Report_&ryr._Q&qtr._v&rundt..txt" dsd dlm=',';
set out4;
put ( _all_ ) (~);
run;

I now know the (~) puts quote marks around all [character?] fields. I found definitions tin Communities about (+0), but I want to know more.

Help is appreciated.

The documentation can be found in the below link, where it says "How to Group Variables and Formats".

_all_, as the name suggests, refers to all variables.

When variables are placed in brackets after the put statement then that is referred to a variable-list.

Great information and thanks for the all the specific links to documentation.

I still don't see any mention of the what (:) or (~) etc means.  Can you help?

The documentation of the LIST mode of PUT statement mentions the ~ and : modifiers.

https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/lestmtsref/p0jcwhe1ofmb49n1xf1q2kc44b0v.htm

Although the requirement that you follow the : modifier with a format specification is false.

The _ALL_ is just a variable list.  Just like VAR1-VAR10 or NAME SEX AGE or  FIRST -- LAST or PREFIX: or _NUMERIC_ or _CHARACTER_ etc.. Variable lists are used all over SAS.

The (varlist) (fmtlist) syntax is part of the PUT statement.  Inside the first parentheses is the list of variables and in the second is the list of formats (and modifiers like ~ or pointer motions like +0).

You can also apply a list of formats to a list of variables in a INPUT statement.

If you ever learned FORTRAN it is like the syntax for a READ or WRITE statement.

        333    FORMAT(3I4,F8.5,A1,1X,A1,I6)
    
    along with a READ statement,
    
        READ(unit,formatStmtNumber) variableList
