PUT, Formatted |
Valid: | in a DATA step |
Category: | File-handling |
Type: | Executable |
Syntax |
PUT <pointer-control> variable format. <@ | @@>; |
PUT <pointer-control>
(variable-list) (format-list)
<@ | @@>; |
See: | Column Pointer Controls and Line Pointer Controls |
Featured in: | Writing a Character between Formatted Values |
Requirement: | The (format-list) must follow the (variable-list). |
See: | How to Group Variables and Formats |
Featured in: | Writing a Character between Formatted Values |
-L | left aligns the value. |
-C | centers the value. |
-R | right aligns the value. |
Tip: | Ensure that the format width provides enough space to write the value and any commas, dollar signs, decimal points, or other special characters that the format includes. |
Example: | This PUT statement uses
the format dollar7.2 to write the value of X:
put x dollar7.2;When X is 100, the formatted value uses seven columns: $100.00 |
Featured in: | Overriding the Default Alignment of Formatted Values |
Tip: | You can specify either a SAS format or a user-written format. See Formats. |
Example: | Writing a Character between Formatted Values |
Example: | This statement places
a hyphen between the formatted values of CODE1, CODE2, and CODE3:
put bldg $ (code1 code2 code3) (3. '-'); |
See: | Writing a Character between Formatted Values |
Example: | This statement uses
the 7.2 format to write GRADES1, GRADES2, and GRADES3 and the 5.2 format to
write GRADES4 and GRADES5:
put (grades1-grades5) (3*7.2, 2*5.2); |
Restriction: | The (format-list) must follow (variable-list). |
See Also: | How to Group Variables and Formats |
Restriction: | The trailing @ or double trailing @ must be the last item in the PUT statement. |

Details |
The Formatted output describes the output lines by listing the variable names and the formats to use to write the values. You can use a SAS format or a user-written format to control how SAS prints the variable values. For a complete description of the SAS formats, see Definition .
With formatted output, the PUT statement uses the format that follows the variable name to write each value. SAS does not automatically add blanks between values. If the value uses fewer columns than specified, character values are left-aligned and numeric values are right-aligned in the field that is specified by the format width.
Formatted output, combined with pointer controls, makes it possible to specify the exact line and column location to write each variable. For example, this PUT statement uses the dollar7.2 format and centers the value of X starting at column 12:
put @12 x dollar7.2-c;
When you want to write values in a pattern on the output lines, use format lists to shorten your coding time. A format list consists of the corresponding formats separated by either blanks or commas and enclosed in parentheses. It must follow the names of the variables enclosed in parentheses.
For example, this statement uses a format list to write the five variables SCORE1 through SCORE5, one after another, using four columns for each value with no blanks in between:
put (score1-score5) (4. 4. 4. 4. 4.);A shorter version of the previous statement is
put (score1-score5) (4.);
You can include any of the pointer controls (@, #, /, +, and OVERPRINT) in the list of formats, as well as n*, and a character string. You can use as many format lists as necessary in a PUT statement, but do not nest the format lists. After all the values in the variable list are written, the PUT statement ignores any directions that remain in the format list.
For example, this format list includes more specifications than are necessary when the PUT statement writes the last variable:
data _null_; input x y z; put (x y z) (2.,+1); datalines; 2 24 36 0 20 30 ;The PUT statement writes the value of X using the 2. format. Then, the +1 column pointer control moves the pointer forward one column. Next, the value of Y is written with the 2. format. Again, the +1 column pointer moves the pointer forward one column. Then, the value of Z is written with the 2. format. For the third iteration, the PUT statement ignores the +1 pointer control.
These lines are written to the SAS log:(footnote 1)
----+----1----+ 2 24 36 0 20 30
You can also specify a reference to all elements in an array as (array-name {*}), followed by a list of formats. You cannot, however, specify the elements in a _TEMPORARY_ array in this way. This PUT statement specifies an array name and a format list:
put (array1{*}) (4.);For more information on how to reference an array, see Arrays.
Examples |
This example formats some values and writes a - (hyphen) between the values of variables BLDG and ROOM:
data _null_; input name & $15. bldg $ room; put name @20 (bldg room) ($1. "-" 3.); datalines; Bill Perkins J 126 Sydney Riley C 219 ;These lines are written to the SAS log:
Bill Perkins J-126 Sydney Riley C-219
This example includes an alignment specification in the format:
data _null_; input name $ 1-12 score1 score2 score3; put name $12.-r +3 score1 3. score2 3. score3 4.; datalines; Joseph 11 32 76 Mitchel 13 29 82 Sue Ellen 14 27 74 ;
These lines are written to the log:
----+----1----+----2----+----3----+----4 Joseph 11 32 76 Mitchel 13 29 82 Sue Ellen 14 27 74The value of the character variable NAME is right-aligned in the formatted field. (Left alignment is the default for character variables.)
