Strings

String variables are only formatted to a length. The format is specified as $N where N is the width.

Length Statement

Often, it is important to specify a string's length before creating it. Observe:

data TEST1;
    VAR="FOO";
    VAR="FOOBAR";
run;

/* variable VAR is 3-wide and contains "FOO" */

data TEST2;
    length VAR $60;
    VAR="FOO";
    VAR="FOOBAR";
run;

/* variable VAR is 60-wide and contains "FOOBAR" */

put Formats

The put function accepts additional formatting details:

-L left aligns the value
-C centers the value
-R right aligns the value

These are appended to the string format:

data TEST;
   VAR2 = put(VAR1, $60. -R);
run;
