LENGTH statement

Learn LENGTH statement in SAS through the exact construct, a dedicated example, a boundary case, and a mastery check.

10 min read • Beginner

LENGTH statement is an atomic SAS lesson inside DATA Step Basics. The example uses the specific syntax, command, API, instruction, or language rule named by this lesson.

Study the construct itself, then change one relevant input and predict the result before running it. That keeps this lesson focused on LENGTH statement rather than on generic SAS syntax.

Topic-specific example

data work.users; length name $40 email $120; input name $ email $; datalines;

; run;
Edge case / engineering note

For LENGTH statement, inspect the SAS log as well as the output data set; type conversion, missing values, and BY-group ordering can change results without stopping execution.
