PUTN(source, format.<,w<,d>>) |
specifies a numeric constant, variable, or expression to which you want to apply the format.
is a character constant, variable, or expression with a value that is the numeric format you want to apply to source.
is a numeric constant, variable, or expression that specifies a width to apply to the format.
Interaction: | If you specify a width here, it overrides any width specification in the format. |
is a numeric constant, variable, or expression that specifies the number of decimal places to use.
Interaction: | If you specify a number here, it overrides any decimal-place specification in the format. |
Details |
If the PUTN function returns a value to a variable that has not yet been assigned a length, by default the variable is assigned a length of 200.
Comparisons |
The PUTC function enables you to specify a character format at run time.
The PUT function is faster than PUTN because PUT lets you specify a format at compile time rather than at run time.
Examples |
The PROC FORMAT step in this example creates a format, WRITFMT., that formats the variable values 1 and 2 with the name of a SAS date format. The DATA step creates a SAS data set from raw data consisting of a number and a key. After reading a record, the DATA step uses the value of KEY to create a variable, DATEFMT, that contains the value of the appropriate date format. The DATA step also creates a new variable, DATE, whose value is the formatted value of the date. PUTN assigns the value of DATE based on the value of NUMBER and the appropriate format.
proc format; value writfmt 1='date9.' 2='mmddyy10.'; run; data dates; input number key; datefmt=put(key,writfmt.); date=putn(number,datefmt); datalines; 15756 1 14552 2 ;
